I am taking a hard look at the X1 for simply for the portability. The lack of internal optical drives doesn't turn me off because I will always have wireless access on campus and can access my fileserver at home. But the 12.1'' widescreen conerns me a bit. I've never used that small of a screen for simple surfing and word processing. Is this a valid concern? Plus for the price of the X1 or less, I could easily get a gen-2 XPS with some of the $750 rebates Dell has been running. Suggestions?
