The $1600 Keyboard
If you want the ultimate in luxury for your computer setup, you should have an Art Lebedev's Optimus Maximus keyboard, which costs a reasonable $1600. The reason for this price is that it has 133 tiny OLED display keys. In other words, each key is a tiny screen, that can be programmed to show whatever you want on each individual key, including images and movies. It is currently sold out at ThinkGeek.com.
