Good question - I'm thinking of purchasing the exact same PDA. When I was in HKG last month, a guy at the electronics store near 'The Wing' let me try one out for about 30 minutes, which was jolly nice of him. I didn't purchase though, because I wanted to read some reviews and so on first.
Anyway, it's a pretty nice piece of kit and runs Palm OS 5.2.1, with built in wifi and camera.
Can anyone post anything else about this PDA?
