Warning: in the past couple of years, manufacturers that shipped perfectly decent products have started replacing good components and build quality with unusable crap. If something has to sit in front of you for hours, you want materials that do not hinder you while you are operating. Expect the successors of some formerly very good lines to be noisy on touch (as in, tapping on a cardboard box), to be unpleasant on touch (with reference to touchpads), to stink. Plus, heavily tinted displays with spotlights, etc. Nowadays, you must assess it physically, not just on on-paper specifications.
