Samsung has not messed with the Bluetooth HID profile in the Galaxy Note firmware. This means you can connect common Bluetooth peripherals like Bluetooth mouse and keyboard. This could be useful for some. So I tried various mouse and keyboard with it.
1) Apple Magic Mouse – Works like a charm, including two finger scrolling
2) Apple Wireless Keyboard
3) I-tec bluetouch 243 laser mouse
4) Logitech DiNovo Edge
5) Apple Magic Trackpad
6) Microsoft wireless laser mouse 8000
