Today I was able to test the X220T at a store. Everything worked fine for me, except that the multi touch did not really worked.
So my problem was: Pen worked as it should. 5 fingers to lock up the screen worked. 4 fingers to switch between programs worked. But when I wanted to zoom in or out like on the iSomething it did not work. Even scrolling in the Windows Internet Explorer did not worked. I always marked something, but never scrolled. Opening up the simple tap by tapping twice on the screen with two fingers did not work as well.
Back on the touchpad zooming and scrolling worked with two fingers...
Did anybody experience that before? Is there a menu where you can change settings? Or do you have to learn the tablet the gestures you want?
