Anyone out there using a controller, BT or USB, to play games on their 300? I know Nyko is coming out with the playpad which should work great with this tablet, but I'm not sure when they'll be available for purchase. And Gamestop offers a controller for use with tablets, but the first reviewer says it won't work with his 300. I love playing games on my tablet, but I'd love it even more if I could play them with a controller instead of the touchscreen. Thanks.
