I was pleasantly surprised as a rumor had been going around the interwebs that the G1's hardware was too puny for the latest Android update. More importantly, the update seems to have fixed the G1's number one problem. It has suddenly become a much faster device. It's not as fast as my Pre is on its best days but it's definitely competitive.
This is a pretty exciting development. The G1's problems had soured me on Android but now with its latest update, I'm starting to de-sour.
