No one ever said a modded MacBook Pro was gonna be cheap. Last week Modbook announced that it would be going ahead with pre-orders on the Modbook Pro today, but didn't really touch on pricing. As ordering begins, the company's attached a $3,500 starting price tag for the honor of controlling your 13.3-inch Mac with a pen. The Modbook Pro, which is set to start shipping in the middle of next month, runs Mountain Lion and features a 2.5GHz Intel Core i5 processor (upgradable to a 2.9GHz i7) and memory and storage up to 16GB and 480GB, respectively. If you're aching to get your hands on one of these Frankensteinian tablets, you'll have to plunk down a $500 deposit.
