The perceived poor performance of the GPS does worry me. The primary reason I'm considering a G1 over an iPhone is that I want to use the GPS with (hopefully available soon) offline topographic map software (more detail at http://groups.google.com/group/android-discuss/browse_thread/thread/13c88c7d70c420). I hope many more detailed reviews follow since I never found a very technical GPS performance review of the iPhone 3G (though some have complained, my playing with friends' units so far has been adequate). I'd like to see something like the numbers in http://gpstekreviews.com/2007/04/14/gps-receiver-chip-performance-survey/ though this chart is for chips not entire systems. I realize the antenna choice and LNA performance are going to affect the final performance. I'd like to know the performance for all three cases of offline, GSM network, GSM + 3G network, time to first fix with an open sky for hot start, warm start, cold start and in addition some way of quantifying the performance of the unit in a shaded environment (e.g. tree canopy).

The kind of Android phone I'd really want is not the G1, but I'm not sure I can wait for my ideal phone assuming it would ever be made. I'd want a much bigger screen, at least a 3.8" 800x480 if not a 4.2" 1280x720, unit should be touch screen only, ruggedized and waterproof with perhaps a separate keyboard that might not be waterproof that magnetically could attach to the back and wirelessly transmit keystrokes to the main unit.

I hope this GPS on the G1 isn't crippled so fundamentally it can't be fixed with firmware/software updates. If not, I sure hope SiRF (an OHA member) isn't the one making the chipset for HTC - that would be embarrassing for them.

At 546 ppi, this is too dense for me since I can no longer focus much closer than 10". But if you can focus down to 6.3", then why not? I'm fine with around 200-300 ppi myself so this screen at around 4" (with a viewing distance of about a foot) would be great.

d = 60 / (atan(1deg)*ppi) is the distance to view for 60 pixels per degree.
