an iPad, there's a good chance your tablet already disappears for long stretches, only to come back covered in tiny fingerprints. Today's Appmates announcement from Disney will likely have plenty of parents seriously considering the purchase of a second tablet for the home. The Cars toys are meant to be driven across the top of an iPad, interacting with a downloadable Cars 2 Appmates app, which lets kids drive around courses, race and complete missions. The app will be offered up as a free download through iTunes, and the cars will run $20 for a two-pack -- the different toys unlock different features, according to Disney. The toys will be made available in October through Apple and Disney Stores and various retailers. Press info and a video after the break.
