Two of the guys in our office have the Latitude X300 (last year's version of the X1) and they adore them! They both have the media base that includes the DVD drive and all the extra ports. When they leave the office, it's simply a matter of popping it off the base and walking away, with no cords to unplug ever.

For some inconceivable reason, there doesn't seem to be a media base for the X1.

If it were me, I'd buy an X300 and upgrade the memory and hard drive. The only downside to that is the warranty.

EDIT: It looks like you can get an X300 from the Dell Outlet with 60gig and 1128meg with Dell's 3 year warranty.
