That's what happens when you release a s*** product.
Have you used one? It's a great product.
In fact I bought a Dell XPS10 with Windows RT and I am impressed.
It can fileshare, it allows PowerShell remoting; it's much more flexible than an iPad. Application availability is not nearly as good as for the iPad, but that's not a fauly of the product. (Besides, Mac users know plenty of excuses why application availability is not as important as other features.)
The real problem with Microsoft's Surface is that they did everything in their power not to sell it.
In 2012 Microsoft simply didn't sell the Surface in Switzerland. You couldn't even order it from another country. They just wouldn't sell it to Switzerland.
Then Microsoft made it imossible to order or buy the Surface with any keyboard Dock but the local language one. I wanted an English or American keyboard. Microsoft does not allow such a choice. Dell does, but you have to call them, it cannot be done online. It's ridiculous.
Apple's great advantage is the Apple Store, online and offline.
I bought a MacBook Air last year and I was able to bye the Air with an American keyboard no problem. The only problem with the Air was the fauly battery and the discovery that Apple's solution to the problem of non-replaceable batteries was to ignore the problem. So I had to bring the Air to the local Apple Store and three days later they had replaced the battery (with another faulty one but that was coincidence).
So both companies have problems. Microsoft refuses to sell me things and then complains that nobody buys their product. And Apple finds it acceptable to leave me without my laptop for several days.
But Windows RT is a solid product. The tiles interface is in fact easier and more intuitive than the iOS interface. And the fact that desktop mode exists to run legacy apps (Office and some Windows accessories in RT's case) is a distinct advantage over the iPad. Finally, the inclusion of PowerShell (including remoting) and file sharing is icing on the cake. Apple's iPad does not even come close.
