What is tablet tablet pc

Tablet PCs or Tablets for short are a special type of computers (laptops) which accept user input via the screen. They are mainly of two types although the recent ones offer both types in one screen. One type is called as an active digitizer screen which uses a special pen with a special tip. The other type is the passive digitizer normally found on PDAs like the i-mates and iphone.

Microsoft popularized the idea of tablet pcs as laptops which accpet a unique and more intimate type of user interaction namely the direct user input via the screen instead of the mouse or the keyboard.

...hope that answers your question a bit. :)
