I am liking my x1. I have used a 600s, t20, t40, t61 and now the x1 carbon. But I hate what they did with the Home/End/PgUp/PgDn buttons. They had room, why did they have to mess up the standard thinkpad keyboard layout. My fingers have taking weeks to adjust. Also something is funky with the touchpad. I almost never use it because I love the trackpoint, but when I do it is just not as responsive as it should be.
