I think the weirdest part of all the Surface Pro 3 discussion is how much its usability as a pure tablet is being totally ignored. Whether talking about "lappability" or simply how you can prop it up on a bed/tray table / wherever else.
It's like people are so conditioned to think that 8" and 10" are the only reasonable sizes for tablets that they automatically assume a 12" tablet is just too absurd to even consider as a viable size to use.
12" is kinda large, though. I wonder if it really is as comfortable to hold in your hands as a 10" tablet. That's really my only worrying point so far. Maybe someone with a SP3 or a similar 12" tablet can shed some light on this?
