It's finally here! SiriusXM On Demand has launched, ushering the satellite radio service into the 21st century. The company's promised library of 200 shows and 2,000 hours of programming are online and available for subscribers to stream at their leisure. Access is free for existing subscribers, and available through the web or the SiriusXM apps on iOS. App users can even download shows for offline playback (which we believe makes them podcasts). Now you'll never need to miss another allegedly hilarious episode of Opie & Anthony again. Though, you might be a better person if you did. Check out the PR after the break for a few more details.

Live traffic info likely prevents many a clenched fist meeting steering wheel every single day. A new trial scheme in Frankfurt Germany, however, could prevent even more unnecessary road-rage. The project involves 120 vehicles from a range of manufacturers, loaded with "car-to-x" technology. Cars will communicate with each other, and with general infrastructure, in an attempt to make roads safe and less congested. As well as basic location data, other tools include a brake light that advises the car behind it once activated, and an obstacle warning system to share information on the presence and location of hazards -- as well as what those blockages are. The project is a collaboration between Universities, research institutes, telecom providers -- and of course -- the auto industry. We're keen to see how the trial turns out. Even if it's just to lower our next taxi fare.

Rapid turnaround just may be the name of Facebook's game. Just a few weeks after its SDK 3.0 for iOS reached beta, the new developer tool has surfaced in a polished version. As it's shipping, the SDK continues to emphasize a more iOS-native experience, better API support and slicker session management. Any iOS 6 integration will still have to wait until Apple finishes its software update; Facebook is keeping a separate beta track active to serve forward-thinking developers. The social network's regular members aren't quite getting the same reward, however. The expanded app support is being followed just as quickly by a mobile ad beta. While Facebook is still sparing us from a full-bore marketing assault, it's letting developers pitch their Android and iOS apps from Facebook's mobile portals, with a quick hop to the relevant app store if the title isn't already loaded. While there's no estimated completion date, we have a feeling that this is one Facebook beta where most customers won't mind a delay or two... or ten.

Google has expanded its Maps traffic coverage before, but rarely on a grand scale. The search giant isn't standing on tradition this time: it just flipped on live traffic data for at least the major roads in over 130 cities. Most of the coverage centers around smaller cities in the US, although Google is tipping its hat to Latin America with first-time support for Bogota, San Jose (in Costa Rica) and Panama City. Coverage has also been improved in a dozen other countries worldwide. While the widened reach still won't ease the burden of anyone already caught in a traffic jam, any democratization of smarter driving directions is good in our book.

MetroPCS may not be grand in scale, but it's certainly not lacking for ambition. Just over a year after announcing its eventual transition to Voice over LTE, the carrier has officially launched its VoLTE services. Moreover, it's announcing the first sale of a VoLTE-capable handset at one of the company's Dallas / Fort Worth store locations. The Android-powered LG Connect 4G is the outfit's first (and only, for now) VoLTE-capable phone, but the operator's promising more rollouts and phone options "in the coming weeks." For the consumer, those in range of LTE signals should notice clearer calls, and it's become something of a trend to see carriers (Verizon and Sprint, for instance) moving in this direction as 2G / 3G networks start to show their age. So, DFW residents -- anyone been able to try it out? Let us know in comments below.

We had a fun time trying Sony's SOEmote expression capture tech at E3; now everyone can try it. As of today, most EverQuest II players with a webcam can map their facial behavior to their virtual personas while they play, whether it's to catch the nuances of conversation or drive home an exaggerated game face. Voice masking also lets RPG fans stay as much in (or out of) character as they'd like. About the only question left for those willing to brave the uncanny valley is when other games will get the SOEmote treatment. Catch our video look after the break if you need a refresher.

NFC is used primarily for enjoyable activities, like buying things, sharing content and making QR codes feel old. But Japanese company Elecom is looking to change all that with a compact keyboard that exploits NFC for productivity. The silicon menace requires a companion app and is compatible with Android phones running Gingerbread (2.3.4) and up. If the bundled case had you sold on the peripheral, you may want to reconsider. The retail price is a sizeable 18,690 yen (approximately $240), and what's worse, the battery is neither rechargeable nor replaceable, so you'll have to bin it after the stated six months to a year 18 months (eight hours a day) of life. Still interested? Then head over the break for a video demo from Norwegian co-development company one2TOUCH.

A federal appeals court has ruled today that the US government can tap into Americans' communications without worrying over frivolous things like "being sued" by its people. In what most sane civilians will probably see as a depressing loss of protection, a three-judge panel of the 9th US Circuit Court of Appeals ruled that citizens can sue the United States for damages stemming from the use of information collected via wiretap, but not for the collection of information itself. In typical pass-the-buck fashion, Wired reports that Judge Michael Daly Hawkins and Judge Harry Pregerson added the following: "Although such a structure may seem anomalous and even unfair, the policy judgment is one for Congress, not the courts." Alrighty. For those unaware, the back and forth surrounding this issue extends back to Congress' authorization of the Bush spy program in 2008, and more specifically, a pair of US lawyers and the now-defunct al-Haramain Islamic Foundation -- a group that was granted over $2.5 million combined in legal fees after proving that they were spied on sans warrants. The full report can be found in the PDF below.

Despite improvements, working conditions are still a sore point in China -- and China Labor Watch wants to emphasize that no company is exempt from scrutiny. The rights advocacy group claims that, on top of pushing mandatory overtime and poor overall conditions, Samsung contractor HEG Electronics has allegedly been employing at least seven underage workers at a Huizhou plant making phones and DVD players. Not surprisingly, Samsung has been quick to defend itself, asserting that it found "no irregularities" in two separate inspections this year and that it plans a third as a response to the new accusations. Who's telling the truth is still up in the air, although China Labor Watch is taking aim only after going undercover; it's long been suspected that contractors whitewash their labor practices when they see corporate inspectors coming from a mile away. If there's any substance to the allegations, Samsung may be the next tech giant taking action to mend a bruised public image.

Just as you've cozied up with "Tahiti" and "Cape Verde," AMD has returned to grow its "Southern Islands" family of graphics cards with four fresh FirePros, offering up to four teraflops of graphics computing power. That spec can be found in the company's new W9000, which is capable of four TFLOPs single precision and one TFLOP double precision with a price tag just shy of $4,000. That behemoth of a card offers 6GB of GDDR5 RAM and requires 274 watts of power. More humble members of the fam include the W8000, which has the same form-factor as the higher-end W9000, but eases back on the specs, consuming 189 watts of power and carrying a $1,599 price tag.

We had a chance to take a closer look at both cards at SIGGRAPH, and while they packed a significant amount of heft, you'll likely never take a second look once they're buried away in your tower rig. Fans of smaller housings (and price tags) may take notice of the W7000 and W5000, which are both considerably more compact and require less power to boot, with pricing set at $899 and $599, respectively. Those cards were also on hand for our demo, and can be seen along with the top two configs in our gallery below. You can also sneak a closer peek in the hands-on video after the break, and glance at the full specs over at our news post from earlier today.

You don't get to unbox anything or have that new-camera smell, so how much does the Canon 7D v2 firmware really transform the now three year-old model? The answer depends a bit on what you do with it, but for most users the Japanese maker deserves kudos from bringing new functionality to the model. Two changes stand out in particular, the first being a bump in the number of burst RAW images from 15 to 25, a boon for action shooters. The other biggie is manual audio level adjustment, saving videographers from the whims of automatic audio levels. Other tweaks include in-camera rating, resizing and editing of images; a max auto ISO setting; GPS compatibility; file name customization; time zone settings; and faster magnification scrolling and control screen adjustment during playback.

To test the burst and audio functions, we got our own mitts on the firmware. Prior to updating, we put the rapid-fire 8 fps camera it through the wringer and grabbed about 16-18 RAW frames in a burst. With the v2 firmware we caught exactly 25 frames before it halted, and did it again numerous times with only an occasional stutter. As for audio, the new manual setting is still a far cry from dedicated sound level dials -- on the 7D you'll need to preset the audio before filming, and are stuck with that level until you hit 'stop' again. Still, it beats the previous automatic way, which was so unusable that it forced many pros into buying external audio recorders to get anything decent. A quick test confirmed the new adjustment worked well, giving usable audio in most conditions with both internal and external mics while requiring just a little fiddling beforehand to set levels.

While hardly turning your 2009-era beast into an all-new DSLR, the new functionality brings the software in line with newer models, and still keeps the 7D near the top of the APS-C heap in many categories. Swapping out the sensor would be the only way to bump the one area where it now lags, low-light performance -- but you can't expect everything from a $1,500 shooter.

Gone are the days when $50 got you a flip phone that could make calls, send texts and shoot super-low-quality thumbnails. T-Mobile's myTouch offerings aim to provide all the functionality of a top-tier smartphone, coupled with the kind of hardware and software top-tier handsets were offering a year or two ago.

After letting HTC and LG have a go at the myTouch series, T-Mobile tapped Huawei to design its latest devices, the myTouch and myTouch Q, a garden-variety slab and a full QWERTY slider, respectively. This time around, the carrier chose phones with more expansive 4-inch, 800 x 480 displays, among other improvements to the design and internals. Unfortunately, software wasn't considered in the upgrade: both of these run the aging Android 2.3 OS. Suffice to say, skinned Gingerbread is likely to turn off some shoppers, but it's still worth asking if people on a budget might appreciate these devices when they go on sale Wednesday for $50, post-rebate. So are there any redeeming qualities to speak of, if not the software experience? Read on to find out.

T-Mobile myTouch and myTouch Q review

Well, the good news, as you already know, is that Office RT will be preloaded on all Windows 8 RT tablets -- at least in preview form. The bad news, even if you spring for the full version, you may be dealing with a limited product. Word on the street is, that in order optimize performance and battery life, Microsoft pulled a number of features from the ARM-friendly version of its productivity suite. Among the missing features is support for macros, third-party add-ins and VBA scripts. A small number of other features are also reportedly on the chopping block, but without a final product to put our fingers on, it's not clear which ones are getting axed.

Think those are some pretty slick graphics in your Galaxy S III? Samsung's latest smartphone packs some mighty graphics prowess of its own, thanks to the Mali-400 MP GPU, but once you spend a few minutes with the Mali-T604, the company's next-generation chipset, the improvements become quite clear. After seeing the Mali-T604 in action, as we did at SIGGRAPH today, the capabilities leave us hopeful for the future, and perhaps feeling a bit self-conscious about the silicon currently in our pockets. The reference device on hand was operating in sync with a variety of unnamed hardware, protected from view in a relatively large sealed box. We weren't able to squeeze many details out of ARM reps, who remained mum about the demo components, including clock speed, manufacturer and even fabrication size. What we do know is that we were looking at a quad-core Mali-T604 and dual-core ARM Cortex-A15 processor, with a fabrication size in the range of "28 to 40 nanometers" (confirming the exact size would reveal the manufacturer). Clock speed is also TBD, and the early silicon on demo at the show wasn't operating anywhere close to its top end.

In order to experience the T604, we took a look at three demos, including Timbuktu 2, which demonstrates elements like self shadowing and depth of field with OpenGL ES 3.0, Hauntheim, which gives us an early look at physics simulation and HDR lighting with OpenCL, and Enlighten, which rendered silky smooth real-time illumination. You can see all of the demos in action after the break, and you can expect T604-equipped devices to make their debut beginning later this year -- ARM says its working with eight manufacturers to get the licensed tech to market as early as Q3.

Microsoft already has licensing agreements with the companies accounting for the vast majority of Android devices on the market, but it's not done just yet. The latest to come on board is Sharp, which has signed a deal that will allow it to use Microsoft's Extended File Allocation Table file system (otherwise known as exFAT) on its Android-based devices -- that's a slightly more specific agreement than most others, where the contents haven't been disclosed. While Sharp isn't exactly a major smartphone player here in North America, it is in Japan, where it had a market share of 17.5 percent in 2011 (second only to Apple). As with other similar deals, this agreement will see Microsoft receive royalties on all Sharp Android devices sold, although neither party has commented on the specific terms. You can find the official word after the break.

Plextor's newly launched M5 Pro is angling to be the top dot on the SATA III SSD spec charts -- and looks like it will mostly succeed. The Marvell Monet controller lets the unit hit a continuous 540 MB/s read and 450 MB/s write speeds for the larger models, as well as a hefty 94,000 read and 86,000 write IOPS. Those figures would put it ahead of or alongside most of its competitors except in steady write speeds, but Plextor claims that hustle is not the model's only trick. It also makes use of "True Speed" tech to minimize performance drops with age, uses 128-bit error correction to eliminate data inaccuracy and offers 256-bit full-drive encryption. The 128GB, 256GB or 512GB drives will be available mid-August for prices that have yet to be determined, but it's likely to be well north of its budget namesake, the M5S. You'll find the full PR after the break.

Apple has been filing more than its fair share of NFC-related patents, but it was just granted what could be one of its more important wins at the USPTO. The design for an "on-the-go shopping list" app would help buyers find and pull the trigger on deals through every tool an iPhone has at its disposal, whether it's taking a snapshot of goods with the camera, punching in the UPC code by hand or tapping an item for an NFC-based "touch scan." We'll admit that we're a bit disappointed at how NFC is used, however. As with an earlier filing, the very short range wireless is kept largely to price comparisons and adding products to a list for a purchase from a store clerk later on, rather than closing the deal outright as we've seen with Google Wallet. The original 2008 filing date will also have seen a lot of water flowing under the bridge; there's no guarantee that any enthusiasm for NFC from the iPhone 3G era will have transferred to the present day. Accordingly, we would be careful about drawing any connections between iOS 6's Passbook and Apple's ideas from four years ago -- even if Apple has regularly been a never-say-never sort of company.

We have ad-supported e-reading today, but the ads always sit on the periphery at most. That makes us more than slightly nervous about a newly-granted Microsoft patent for contextual e-book ads. The development would make the pitch based on not just targeted pages but the nature of the book in question: a sci-fi novel might try to sell lightsabers, and characters themselves might slip into the ads themselves if there's a fit. Promos could be either generated on the spot or remain static. Before anyone mourns the end of unspoiled literature, just remember that having a patent isn't the same as using it -- Microsoft doesn't have its own dedicated reading app anymore, let alone any warning signs that it's about to pepper our digital libraries with marketing. If the Newco partnership results in copies of War and Peace bombarded with Black Ops II ads, though, we'll know where to place the blame.
