The tablet functionality allows you to do things such as take handwritten notes with the Tablet Digitizer Pen or even use your finger to interact via touch screen on select models. Available Intel Centrino Pro processor technology on the ThinkPad X61 Tablet delivers hardware-based security and enhanced manageability, along with exceptional performance and outstanding mobility. And like all X Series notebooks, the X61 Tablet is ultraportable and offers extremely long battery life.
