12" is too big for a tablet for me, unless MS can work some magic by shrinking the bezel on the current SP2 and expanding the dimensions by just a wee bit.
but all this could just be nothing is the SP3 or whatever the new device is never sees the light of day here.
12 inch tablets serve a very different purpose from 10 inchers leh. I've been using an Asus Eee Slate for work for years because that extra real estate is essential for the pen work that I do daily. The Surface Pro that I use trades that off for portability, funny as that sounds to people who might be used to iPads.
The way I see it is this - 12 inchers are for professional grade stylus-based work, 8 inchers are for mobile content consumption and maybe lightweight productivity. 10 inchers can serve both purposes but will excel at neither. But having said that, I lent a colleague my Surface Pro once and she ended up buying a Surface Pro for herself right after that... that's how awesome that thing is for my work.
Unfortunately for MS, none of us really see the need to upgrade the Surface Pro. The short battery life is still more than enough for our use
I do wish there'll be more shops importing the SP3 though... the urge to upgrade isn't a need but an itch
