It seems like it's been a while since we got a good, juicy Apple tablet rumor. So, how about this one: The company is working on three different-size tablets. There's the already rumored 10-inch, a 13-inch, and a 15-inch.

According to Gizmodo, this rumor "comes from a source that has always been 100-percent reliable." Said source apparently spotted the two larger prototypes at a Shenzuen, China factory. One of the two was running OS X Leopard. Both models were apparently aluminum, "[in] the shape of big iPhones."
