How can it be a Windows PC if it does not run Windows programs? The Pro version will be a Windows PC, but calling current Surfaces "Windows PCs" is bad Microsoft marketing (or a blatant lie, if you prefer).
If people understand better that Surface is Android from 24 months ago that can run Office that you are prohibited to run in all the most likely settings, it would be better for everyone including Microsoft.
I guess any tablet will die of obsolescence in 2 years. If you believe that in a year Surface will get enough apps to be on par with Android, or you are one of those who is determined to make that happen, or you just badly need a cut down mobile office for personal use - buy Surface. If not, either buy iPad or Android or wait for the real thing - Surface Pro.
Any other advice is a disservice for the readers.
P.S. I refuse to call any device a computer if it is impossible to develop for it on it. Thus, Android tablets and Surface Pros are computers, Surfaces and iPads are merely gadgets.
