I saw this PDA at Sakuraya yesterday. It's special feature is that it has a 640 by 480 display. That's at least 4 times what any other PDA has. That does make it of course larger than other PDA but it's not all that much larger. It would probaby still fit in most pockets.
I'm not sure if having a 640x480 display is a plus though. It's not running the pocket version of CE. It's running regular Window CE meaning it has a desktop and a start menu etc but still, it's kind of cool 😉
