Apple back in the PDA market?

The rumors are flying. There is talk of Apple re-entering the PDA market, but just how is a mystery. Some say it will be through this new color iPod in the rumor mill, others say it will be a new device of it’s own. Will Apple revamp the iApps to be more powerful. Who knows, but I believe in the next few months there will be much more for us to all speculate about. I for one, would love a PDA that ran OS X and could place calls.
