+1 to ThinkPad, good quality, great for Linux, and TrackPoint which is the vim of mice (no moving off the home row).
(Pair the ThinkPad with a Linux desktop using an external USB "ThinkPad-style" keyboard, and you've got TrackPoints + exactly the same keyboard layout (and OS layout/key bindings, etc) across laptop and desktop.)
