I think you missed a big differentiator (well actually you missed several)
No. 1. Battery life. The real Surface (not the near useless RT one) is rumored to have an extremely short battery life. True or false? I'll tell you this - battery life is never a concern for me with the iPad. Never. I don't even have to think about it. Using a Surface must be like flying a glider - you are always conscious about how far you are away from a (air)port to land (charge) it.
No. 2. With regards to the screen you compared the expensive Surface to Apple's cheapest bargain basic iPad (full-size). Is that fair by any stretch of the imagination? Are you telling me that as a tech pundit you haven't even looked at an iPad 3 or 4 yet? If you haven't, just how are you qualified to be writing this article since anyone even considering a Surface at its high cost would very likely also be considering purchasing an ipad 3 or 4, and not a bottom basement iPad 2?
No. 3. You're a user of a Windows phone, and not one of their near immediately superannuated 7 models, but a spanking new 920. Believe it or not, you are in a very small minority. You consequently must possess a built-in bias no matter how much you deny it. iPhone users have accumulated numerous apps and working styles and workflows (iCloud is a big one now) and all of them just work, immediately, on the iPad. Actually better in most cases, because of the iPad's bigger screen and the fact that most iPhone apps work in an acceptable manner on the iPad. You make no mention of this. Call it the iOS ecosphere or whatever you want, but it is big and vast To ignore it in an article like this you must either be nearsighted or biased.
