"In the movie Contact, when revealing to main character Ellie Arroway (Jodie Foster) that there is actually a second space travel machine that was being built at the same time as the first one, but in secret, S.R. Hadden (John Hurt) says, why build one when you can have two at twice the price? Apple, it seems, may have the same line of thinking.
By now, weve all seen the iPad and know just about everything about it that we possibly can. But did you know that the secretive company may actually be hard at work on a second device already? Now, before I say anything else, take this information with a grain of salt. While it originated from a good source, it was a second-hand source. Meanwhile, Ive corroborated some the main details with another source, but not some of the smaller ones. That said, from what Im hearing, Apple is pretty far along on work on second tablet device. A bigger one. And this one may be much more like a Mac than an iPhone."
