There are a bunch of things that I would love to see make their way into a laptop. One that ticks a heap more boxes is Lenovo's Thinkpad W700ds. Apart from its huge main display, we get a pop out extra display on the side. The built in WACOM tablet is a super idea and with vast amounts of grunt under the covers to drive everything.

Where should/could things go from here? Perhaps the second screen could fold upwards instead, that way it can either be atop the first or it can all fold down to make a tablet - which could even be a Cintiq active device - cool (maybe detachable for that).
