Our good friends at Mahalo Daily took this short look at the Axiotron ModBook, which (you've probably seen) is a modified MacBook that's been turned into a tablet computer. I learned a couple of interesting things about the device -- first of all, it's not a touchscreen, it's really a tablet, which means you need a stylus to use it. Also, Apple is approving, if not actually supportive, of these things. They're supplying the MacBook bases to Axiotron as an "Apple Proprietary Solution Provider." One could infer from this that Apple doesn't think there's a big enough market for these to make it worth Apple's making an iTablet anytime soon.
The lovely and talented Veronica Belmont also runs through a few practical applications of the device, which I'd imagine are pretty standard on any Tablet PC -- the big draw here, obviously, is that it's a Mac, and you get all the software and UI-shininess contained therein. I don't know that I'm any more inclined to buy one after watching this (I kind of like my keyboard-laden PowerBook, to be quite honest), but it's cool to get a fun look at them in action.
