A netbook is not a tablet pc; it's a mini-laptop. Nowhere does the author refer to a tablet pc. Indeed, he specifically mentions the Dell Mini 9 netbook, which has been on sale for the past year.
Sarcasm... The 'Mac Tablet' that has been rumored forever is an Apple version of the TabletPC. He claimed to have a 'crude version' of a the rumored 'Mac tablet.' It's hard to have that when the Mac tablet's main feature is a touchscreen. I doubt the Dell netbook has a touchscreen. Ergo, he does not have a 'crude version' of such a device unless your definition of 'crude' includes 'missing the most important feature.'
