Go with the Desire Z/ T-Mobile G2. I have an ongoing comparison going on between that and the N810 here: http://talk.maemo.org/showthread.php?t=68800

BTW, my wife has the Global Droid 2. It functions very much like the G2, is waaaaay more durable, but seems to crash at the most random times. (For example, we have to remove the battery sometimes to reset it.)
