In Handhelds

I was crusing on Ebay and saw one of these Contraptions. Does anybody know of anyone that has got one or maybe know if it's really lame (or not)?

Google wasn't being as nice as usual to me (I guess I don't know the magic words) and I couldn't really find much information on it. All I could find was places selling it. And they of course are going to act like it's the greatest thing EVER.

Try to find some reviews about the "". I only heard good stuff about it. It's a bit pricy, though.
