Re: Is GPS a major deciding factor in device choice?
After traveling the world with the Kaiser and the Touch Pro, HTC/Qualcomm's GPSone basically taught me it's better to get something separate.
With the built-in, it would drain the battery, over-heat the phone, reboot the phone often due to the stress, have major problems getting signal due to the undersized GPS antenna, lag and locking issues due to the undersized antenna, and basically life-threatening due to the poor GPS performance which changes between ROM/radio releases.
However, once I switched to an external BT GPS (QStartz Q-1000X for instance) with these same phones, it works transparently as long as I've set up the "External GPS" settings, battery drain isn't an issue anymore, overheating doesn't happen so I don't have to hold the phone to a A/C vent anymore, I can get signal in a train/bullet train/cruise ship/inside buildings/etc, I have the opposite problem of GPS wandering even when stationary instead of lag, really good nav response from Garmin and Navizon, and data trails that can be exported to Google Maps/Earth.
Only nits is the external GPS only lasts a week on a charge, and I have to manually download AGPS data, if I want faster locks (I could just leave it on and not turn it off and not lose lock instead).
So, that's my take on converged GPS, esp with HTC/Qualcomm devices.
