iCade arcade cabinet for iPad starts selling at $100, already on backorder

Humans, they just love mixing the old with the new. To wit, the iCade gaming cabinet for the iPad, an April Fools' joke that was just a fun idea this time last year, has gone and turned very real, replete with FCC certification and now a pre-order page. The Bluetooth-communicating iPad enclosure seems to have originally been on sale for immediate delivery, but ThinkGeek has burned through its first shipment of units faster than you can say "Atari's Greatest Hits." The second batch of $100 iCades is expected by May 20th at the very latest, although orders are being taken only from the US for now. The rest of the world needn't despair, however -- we hear building one of your own is a pleasurable and rewarding experience.
