I was really hoping that Surface Pro was going to be my next lightweight laptop, switching from an Lenovo X201. The later Lenovos seem to get stuff screwed up, like horrible resolutions or wonky physical layouts. I want 12", 1080p (or 1920x1200), full keyboard (like ThinkPad), and a middle mouse button (like ThinkPad, although if everything else is perfect I can compromise. A newer i7 and 8GB of RAM should do it, I'll bring my own SSD. Touchscreen is awesome, but I can live without it if need be.
I was even thinking of getting a MacBook (!) but I hate the look and keyboard (plus Windows support isn't always great).
All the slim "ultrabooks" seem to be poor in some critical aspect. Why? Is there no good replacement for the Lenovo X201? I literally want to give some company $2K, and no one can step up and take it.
