Most laptops give you a touchpad and a keyboard as input methods. The X201T gives you a lot more.
Some of the input methods include:
- Multi-touch screen.
- Digitizer pen.
- Touchpad (multi-touch).
- External options via USB.
With that many different types of input you will have the choice that best fits your needs. Sometimes you won't like the touchpad or trackpoint, so it's neat to have options.
