I'll be ordering an X1 for one of my staff members, so I'll let you know how it is. Of course, my only other experience with a sub notebook (besides endless Toshiba Portiges that I've drooled over) is an HP Omnibook 600C. The built in mouse is the coolest laptop feature ever, next to the lift-up keyboard of the IBM ThinkPad 760XD. Man, I never should have sold that.....
