There fixed it for you. Its only a matter of time. It is a Windows tablet after all.
The one thing that blows all other tablet out of the water is productivity. You decided to skip that part of the discussion.
This is Surface's (and other Win8 tabs') trump card. With touch friendliness integrated into the entire OS, which is what was lacking in Windows tablets, Windows tablets are really leaving nothing uncovered. No compromise.
And excuse me. Isn't the title of this discussion "Windows vs iPad vs Android tablets?"
Surface is not the only Windows tablet out there.
Personally, I prefer the Samsung Ativ Smart PC 11.6'' with 4G (LTE), stylus and a docking station. Now thats no compromise.
