I personally don't see the huge app differences that a lot of you seem to *see*. I had no problem dropping iOS/iPad asap upon getting a Surface Pro 2 -- and I have never once, since getting SP2 though.. "Oh, if I only had an iPad for this certain app" -- Personally I find the whole app quality argument inconsequential.
As for the apps, iOS, yes still gets preferential treatment, because developers are lazy and are still under the impression that it's the "best" OS to make money. As for those apps being better than Android counter parts, for most of the cases, a resounding no. Better than a lot of current Windows 8 apps? Yes, but not for long.
