I still haven't seen an actual iPad arcade cabinet for sale (all the ones we've seen so far have been made by hobbyists for themselves), but here's a pretty cool case/accessory for your iPhone or iPod touch. Pinball Magic is a little device that you can slide your handheld into, and with the help of a free app, you can play a full pinball game live on a little miniature table. There's a real ball plunger, flipper buttons, a full LED backlit display, and even a Tilt detector, so you can hit all the usual lights and gadgets (albeit in an extremely small form factor) without throwing quarters in at the local arcade. Assuming they still have those local arcades -- I haven't seen one around in a while now.
Unlike the cardboard iPad arcade units, this one's on sale and ready to go -- you can pick it up from Best Buy for US $39.99. Sure, that's a little steep (especially since it only works with the one app), but it's a small price to pay to take yourself back to those heady days of reaching for high scores while pushing a little silver ball up and down ramps. If you happen to pick one up and try it out, let us know how it works for you.
