There is no Bluetooth support on the Fire (the developer page says so), I will probably go to Best Buy and grab a stylus to try out on it though since Sketchbook Mobile is compatible with it.
I would LOVE to go on Neopets though, heh. They're very click-friendly and I like playing their games and getting points. It's satisfying still after all these years. I tried to get my brother to join, but he doesn't like it (pfft, this generation doesn't know what they're missing!).
