Microsoft's surface tablets are signs of big things to come. They're currently too expensive for what they are, but they could find a huge niche. They're portable tablets meant for content creation, not mere consumption. If you want a tablet that will let you draw, take notes, etc. as easily as on paper, iPads aren't even close to the current Surface. The surface pro would have been exactly what I wanted in undergrad physics for a lecture-hall machine. Many artists probably feel the same way now.
Tablets have long been too underpowered to tackle real creative tasks. The surface proves that the hardware has changed, although the cost is still high. I expect the next few generations of surfaces to get cheaper and more refined rapidly. People who love tablets are soon going to want something more than a glorified phone, and the Surface is going to be the go-to option.
Yeah, so MS might dominate the content-creation/student/artist tablet niche. Big whoop. Well, success in any consumer hardware niche might do for MS what it did for Apple. Namely, make them a huge pile of cash and jump-start their supply-chain so they can move into other areas. It might not play out this way. Apple has been looking for ways to make the iPad more content-creation friendly beyond just marketing them as such. Still, iOS on an iPad is a huge step behind Win8 on a Surface pro for creative tasks right now. All MS has to do is keep iterating the Surface and avoid another Vista-style PR blunder with Win9.
