By now, we've 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, I've corroborated some the main details with another source, but not some of the smaller ones. That said, from what I'm 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.
