Does it seem like you've been running Software Update on your Mac more than any other application lately? iTunes 10.1 has hit and Mac OS X 10.6.5 is in the wild, and over in the land of Apple mobile devices iOS 4.2 is about to drop.

Tonight on the TUAW Talkcast, we'll talk all about the state of updates, what's working and what's not, what to expect from iOS 4.2 when it finally arrives, and even speculate about the future of Mac OS X.
