Ya know, I know you've already got the usb keyboard, but I tried one myself and found I didn't like it, it made the tablet flakey, and it didn't want to play nice. So I ended up getting this BlueTooth Palm Wireless keyboard, and aside from a slight case of user issue when I tried to pair it to my tablet (I need to learn to read directions better. ^_^;; heh.), it connected perfectly and worked great. In fact, it feels pretty natural, and is almost as comfortable to use as my regular keyboard.
