So then Macbooks were junk too until a few years ago since they didn't sell well? Same could be said of Macs in general for about 30 years.
Well, first of all you're trying to build an analogy where one doesn't really exist.
But I'll bite a little. First, understand that I moved from Windows to Apple in 2008, and I am now all in. Honestly, there was nothing compelling to me on the Mac side, even after OS X was shipped until Leopard. Before that I was unimpressed and uninspired by OS X.
But the difference here is that Apple brought a new, compelling and fun product to the market in the iPod. It got peoples' attention, and started to pull back the curtain to a lot of dyed in the wool Windows users who had never even considered Apple products. It showed them that perhaps computing and electronics didn't need to be kludgy and stoic.
Along comes Leopard, at just about the perfect time. People who are now starting to flock to the Apple stores because of the iPod are seeing how cool and easy computers can really be.
Then comes iPhone, and wow! The momentum builds.
A couple of years later, iPad. Each of these products pivots off of the others.
Now, let's look at the Surface. Aside from all of the technical downsides of it, and Microsoft's insistence on force feeding its large customer base a whole new UI experience on the familiar desktop that they've been using for 20 years, the reaction of the user is, "Well, I can get this "familiar" OS tablet (that's not really so familiar after all, since MS insisted on making everything so "revolutionarily different"). Ho-hum.
Or I can keep using this intuitive, fun, easy-to-use, stable, quality built tablet that is as familiar as all of the other devices I've come to love (as opposed to tolerate)."
That's why MS went so far out of their way to try to portray the Surface in their commercials as this hip, fun, happening tablet, when in fact the biggest selling point for it was that it was supposed to be the best of both worlds: A tablet like MS should have produced ten years ago, melded with the familiar, no-nonsense, "get my work done" ecosystem of MS. Problem was, it (especially the RT) was really none of those things. It wasn't cool. It wasn't familiar. And it wasn't a no nonsense business machine. By the time the Pro came out people had pretty much tuned out.
Their advertising? It was just lipstick on a pig.
So yes, the Surface is %$#*.
