I still have serious doubts about using the tablet form factor for anything but media consumption. As a photographer, I produce media and none of the tablets out there will run Photoshop or Lightroom. Maybe that $900 MS Surface tablet will, but can I put 16 gig of Ram in one? Big photos need big ram. Is the display capable of color calibration?
For the time being, I'm sticking with Win 7 and my 2 desktops and 2 Laptops. I'll let the early adopters figure it out!
