It just...it seems like this would appeal to a very specific type of person. It's bulky, it's ugly, and it's not cheap enough to give it an edge over anything currently on the market. Bluetooth isn't for everyone, I get that, but nearly every recent Android device that's worth it's weight has at least Bluetooth 2.0, and the number of controllers available are staggering. And yes, the HID support sounds great, but five seconds of Googling combined with a little effort and you can get nearly any available controller to work with most Android games.
If this is your cup of tea, go for it, but I don't think it's for most of us.
