Axiotron, together with distribution partner Other World Computing, is drawing huge crowds at the Macworld Expo in San Francisco this week, as attendees flock to take its new Mac OS X-based ‘ModBook’ tablet computer for a test run. Unveiled on Tuesday, the USD 2279 device is an after-market hardware modification to Apple’s MacBook notebook line. The companies claim it’s the ‘first ever Mac OS X tablet computer solution’. Each ModBook starts off as a MacBook Core 2 Duo but undergoes a surgical operation where its original display and keyboard are severed, then replaced with a new 13.3-inch Wacom pen enabled widescreen display set in a chrome-plated magnesium top shell. The device runs the current version of Mac OS X and utilizes that software’s built-in Inkwell handwriting recognition.
