Keyboards

I just bought a new keyboard/mouse combo today to act as inputs for my laptop when I'm at work. I went with the Microsoft Wired Desktop 500 set and it's pretty nice. There is one, glaring, problem though: the keyboard has a PS/2 connector. Pretty useless on a laptop that doesn't have a PS/2 port!

Why Microsoft would even make non-USB keyboards anymore? I guess I should have gone for the more expensive wireless set. At least the mouse is usable.
