Still, after using a laptop/tablet hybrid with a stylus, it’ll be difficult to go back to anything else. Pen input isn’t ideal in all cases, but it’s extremely useful in certain ones. This is just one of the many reasons why I like the Samsung ATIV Smart PC 500T, and an excellent reason to pick up another device like the more powerful Surface Pro, which marries the Surface RT’s form-factor with better specs and a stylus.
