After manually upgrading the G1 to RC29, I have seen a dramatic improvement in some areas of the system: - Scrolling is much improved and smoother - Battery life (or more appropriately the batter meter) is more accurate - WiFi Is more stable - Swipes and long presses are not as easily mistaken for other screen maneuvers. * Some things that I have noticed (dosn't mean they weren't there before) when a calendar event is shown, the screen blurs and the event is brought to the forefront - neat. * Still no advanced accelerometer implementation (except for PicSay). * GPS is still very inaccurate to the point of unusable (for me). * Battery doesn't seem to get as warm with extended 3G use. * Battery lasts a good 14 hours or more. Letting it drain down is a good idea - seems to "break it in" (?). Thats all I could come up with playing around - feel free to add!
