That's what I did. It's a PS/2 keyboard, but it still works great with the media buttons. Then I just use Windows Media Player and all is right in Heaven.
Yeah, I actually bought the cheapest keyboard I could find in Best Buy and it had pretty slick inline controls along the side. Media and stuff along the right next to my mouse and program controls/launcher stuff on the left, which I don't end up using much.
Works petty good. For a $15 generic brand keyboard, it hasn't disappointed me yet.
