MS seems not have learned from the first windows RT fiasco. What I find most shocking is the bad battery. ARM tech is in theory a very battery friendly platform in its current form.
I do own two surface products and the concept is in general pretty good when you use it for modeling and 2D sketching.
I was surprised to see that Apple did not mention windows running on their ARM hardware even through it is 64 bit for ARM and should run at least in a VM.
