Look, we're not denying a pen can be a useful thing to have on a tablet. The problem is, it can be difficult to explain why you'd want one. You could circle things. You could doodle, if you had nothing better to do. You could obviously write stuff too, though you'd need to have open some sort of software that supports pen input. With a forthcoming app from Lenovo, though, you might be using your pen a little more often. The program, called WriteIt, taps into Win 8's accessibility layer, allowing you to enter handwriting in any text field, whether it be the built-in Windows search tool or the search bar on Engadget.com. Heck, you don't even have to color inside the lines, so to speak; it's OK if your handwriting extends beyond the boundaries of the text box. So long as your jottings at least begin in the box, WriteIt will use optical character recognition to decipher your handwriting, and serve up a list of suggested words you can tap.
