I usually would not post such a deal but I thought that this little bluetooth adapter was cool. It is microscopic! Seriously it sticks less than a quarter of an inch.
This is a great solution for add bluetooth to your laptop or even your desktop. The adapter is tiny and is barely noticeable and is a newer model supporting bluetooth 2.0 EDR (but not 2.1). Especially since RIM has slowly been ramping up the bluetooth capabilities in the latest OS updates.
You can pick it up for $19.99 + $5.99 shipping at Newegg. I just got one for a friend.
