Yet again, you haven't read people's complaints properly and you continue to beat the Microsoft drum.
The MacBook Air is an ultrabook. Price? People (not me!) don't mind paying extra for Apple.. but for Microsoft?? ha!
The Surface "pro" 3 is a tablet, but not quite because it needs the crutches of an "optional" detachable keyboard and a pen!
Sure, you can run your dying desktop applications - but not when in "tablet mode" because they're not even designed for touch! NOTHING IS! [Apart from the scant metro apps - which (in my opinion) look quite nasty even in comparison to my kid's knock-off £45 androids from eBay]. You need to poke at it with your free pen.
So basically, for it to be useful you still need to use it as a laptop... and even then, jesus christ.. just look at that keyboard.. JUST LOOK AT IT!!" Beyond typing "I'll be home in a bit", it's only use is a built-in screen protector.
So you have a mediocre tablet, and a mediocre ultrabook, and all the delights of Windows (a/v, botch tuesday, crapware) rolled into one.
I've wasted my money on a Dell venue, so I know exactly what I'm talking about with desk/laptops squeezed into a slab, and since getting it I've also hardly used my laptop, too... because my Wife is always on it!
