It will cost you quite a bundle, but if you really must have your Apple MacBook as a tablet PC then the Modbook Plus service from OWC (Other World Computing) is the way to go.
Starting at $1300, the new Modservice will strip down your existing Intel Core 2 Duo based MacBook, replace the LCD with a touchscreen and add some software to convert it into an Axiotron Modbook, the only Mac-based tablet computer that lets users draw and write directly on the screen.
OWC is an Axiotron Authorized System Manufacturer (AASM) fully certified to convert existing MacBooks into full-featured Modbooks.
You can also opt for some pre-assembled Tablet Macs starting at $2200.
