Why do some keyboards cost so much more than others?

[Syringer]

I picked up a nice wireless keyboard and mouse combo today for $16 at Fry's..and it seemed like all the other wireless keyboards were at least $100, and didn't sêm to provide any sort of added functionality over mine..

I paid $50 for a Logitech MX Duo, because the mouse kicks ass and the keyboard has media keys that I use often (for Winamp) and a cool volume dial.
