This is a dream come true. Ever since I picked up a mobile windows handheld device and hacked it with a 1xrt sprint CF card and made a phone out of it I've always wanted to carry around some kind of windows experience.
Apple makes incredible hardware, and I'll always remember them as the incredibly genius company who released the ipad. But in terms of software they've never been my cup of tea, making things too simplistic for no good reason in iOS. They've made a huge amount of money from keeping iOS hamstrung and stuck in the past and it's good to see Microsoft give them a kick in the pants. I will bet that with a full version of Windows on a tablet Apple is going to finally realize they need to beef up iOS. The surface reads like a long list of the obvious stuff that Apple refused to put into the ipad, stylus and handwriting recognition, a keyboard solution, a full OS, USB, microSD, etc., all in a hardware package which so far is being reported to be as good as the ipads.
My only concern at this point is battery life, that would definitely be the make or break for me. I have quite grown used to 10+ hours and not having to worry about battery life anymore and don't think I could ever go back to the laptop days when I'd always be hunting for an outlet.
