Mad props for posting responses so quickly. I'm familiar with Android but new to using the actual devices, so I really appreciate it!
Anyway, to point, if you can make it to 7pm with GPS and WiFi running and no battery conditioning, that's a H3LL of a lot better than the G1. With moderate 3G usage, WiFi rarely on, NEVER using GPS, and the screen brightness way down, I could only just get to 4pm after coming fully-charged straight off the car charger at 8am. It was irritating having to pack up the wall charger every morning... (The capacity was barely more than my SE TM506's 950mAh.) I had no intention of spending MORE cash for a bigger battery and/or addl. charger and still being stuck w/o a proper headphone jack...
I'm really looking forward to this phone, acknowledging certain issues, notably the pointless "Cube" UI's button instead of a Search button, but more importantly the disappointing memory specs and apparently unimpressive CPU. Especially for the anticipated premium price. (For what?)
