My complaint/concern has to do with deeply recessed keyboards. Whenever I'm not in an "optimal" location, e.g. a conference room, café, etc. where work surface heights tend to be higher, the front edge ends up pressing into my wrists.

I've found it frustrating that so many laptop designs have incorporated this aspect. Smaller body sizes tend to help, although the 13' Mac and Mac Pro nonetheless still seem to have it in spades. Also, widescreen formats have made the overall "depth" that they have to work with, when shoving that keyboard to the back, less -- although I'd prefer more vertical in the screen dimensions, and designers nonetheless get the keyboard too far back for my comfort.

(I strongly dislike actually having the thing on my lap.)
