Mac PDA coming?

Fresh off the release of their Mac Mini and iPod Shuffle, O'Grady's PowerPage is reporting a rumor that Mac is developing a brand-new style of computer, somewhere between a PDA (like a Palm, or even Apple's old Newton) and a full-size tabletPC, running off MacOS and able to directly communicate back and forth between all other Apple devices. Even more intriguing, apparently the device is going to be a "fold-out" kind, kind of like taking a PDA and one of these fold-up keyboard and marrying them into one permanent device. Hmm, hmm, hmm... (Thanks to Gizmodo for pointing this out.)
