For anyone that is considering buying a new keyboard and has over $1500 to spend on it you might want to take a look at the new Optimus Maximus keyboard from Russian artist Art Lebedev. Each of its 113 keys is a tiny 32x32 pixel OLED screen. The images on the keys are controlled by a memory card that is inserted into the back of the keyboard. In this manner the keyboard can be reformatted for almost any application or use.
As of right now no one but the people that preordered the keyboard will be able to get ahold of one except for those willing to pay an even greater premium for buying one off of Ebay. The keyboard itself sells for $1564 but one unit recently sold on Ebay for $2700!
