For: Nostalgia gaming buffs who own iPads.
The iCade turns your iPad into an old-school gaming device--no quarters necessary. After you assemble the cabinet, simply mount an iPad inside, download an iCade-compatible app such as Atari's Greatest Hits or Super Mega Worm, and then pair it with the iPad via Bluetooth to start playing.
The iCade is a little gimmicky, and it won't stand up to serious arcade play, but it looks great on a desk or countertop and it makes a great gift for any gamer who prizes the portability of an iPad but yearns for the classic arcade cabinets of the past.
For tech bonus points, consider jailbreaking an iPad and installing the iMAME4All arcade game emulator; that way, you'll be able to play arcade classics that you legally own.
