I used a coworker's, I don't know if they have floor models anywhere.
I admit it, when I first heard about it, I really wanted it to be tolerable (my expectations were reasonably tempered), but I was let down. I only used it for about a half an hour, but the experience left me more frustrated than anything. I suppose a software update could solve a lot of the usability problems, but for now I can't justify spending any amount of money on it.
The market doesn't really *work*, and that's a big problem when the Android app ecosystem is so dependent on the market model. Sure, there's sideloading and third party app stores, but many official apps aren't available as apks. But it sounds like the limited market support is going to be removed completely. So I dunno, it's a judgement call like anything else. But I'm a pretty avid Android fan, and I was simply disappointed by the tablet.
