Some mini wireless keyboard devices ...

I finally bought this one for HK$200.

Mini Wireless Bluetooth Keyboard
IRXON KB850

Pros: resemble a regular pc keyboard;
Cons: without a mouse/pointing device. Anyway, it works fine for me 'cause I am keyboard-phile/a keyboard ninja. Besides, I mainly use it to remote control winamp. It is much more convenient to control winamp via keyboard.
