F200 is basically the F100 with a touchscreen. It uses AA batteries (2) and eats them for lunch. I have an F100 which is a little better on batteries but is basically the sae thing. Amiga games on it were hit and miss. It's a little slow.
Just got a GP2X-Wiz which also is available right now and performance is much higher plus touchscreen plus rechargable battery.
Pandora sounds nice, but isnt available and who knows if they'll make their target date. I would never order anything a year in advance.
