Dammit! I paid $10 for just one black Dell wheel mouse at a computer show last weekend. Well, after shipping, it's probably even...
Note: The cord on this is very short, making it suitable for laptop use, but if you have a desktop with the USB ports in the back, you'll want a longer cord; and if you have a floor-standing tower, you will have to add a USB extension cord. That cools this deal down considerably.
(Edit: The mouse I got at the show was a USB mouse, making the show deal hotter after shipping. But watch that cord!)
