I made the plunge a few years ago to get a gvido device, which is similar. The big problem is the refresh rate on the device. It is incredibly slow to flip pages, which is a big problem when you're playing. I spent $1500, and the device is basically useless because it's so slow. And the japanese based company doesn't take open box returns, so now I'm stuck with it.

If the device could flip pages quickly, it would be an amazing device. It just can't.
