Droid advantages:

1. Keyboard- Huge issue if you like the game emulators and Android is currently game emulator heaven.
2. 3430 chipset is more balanced option. Snapdragon uses clock cycles to make up for weaker DSP and GPU, so is reported to be more power hungry. Phone manufacturers are capping snap anywhere from 600 to 750mhz.

Curious if Google added more memory for apps on their device. I loaded a LOT of apps to the Droid and still had 182mb(edit) remaining.

If the Google device had a KB and the 3430, it would be the best, since I doubt HTC would block the micro sd slot with the battery like Droid
