One thing that's always bothered me is the use of the PC acronym to talk about Windows/IBM-based machines in comparison to Macs. By definition, machines running Mac OS and Windows, Unix, Linux, etc. are all "personal computers." Of course, it's all right to call IBM machines PCs and Macs as separate because we all know Macs are a lesser form of computing.
That being said, one thing I would buy in a heartbeat is a handheld that has an OS X base. I'm not too enamored with Pocket PC and I really dislike Palm OS. But an Apple handheld would be a pretty cool way to get even more familiar with OS X without having to shell out $1200 on a G4 iBook.
