I have been testing the Orbit2 for nearly 3 weeks now, and having owned pretty much all the previous XDA Touchscreen models, can confidently say it's the best yet
Daron's review covers everything admirably, but my highlights are the flush screen, and TouchFlo interface, the increase in memory and the lightening fast GPS signal aquisition.
The device has been rock solid, and hasn't needed a forced soft reset since I've had it, maybe due to the extra memory.
Dislikes are small- I still don't like the scroll wheel in the 'Action' area, preferring my previous HTC Trinity's side mounted jog dial. And I don't like CoPilot Live 7
Obviously that's a personal opinion and others love it; having the main files in ROM takes up 8MB of useful space, but at least there is plenty spare.
