The Beard has some good insights in his Microsoft forgot to solve a problem post on the Microsoft Surface.
What occurred to me is that Microsoft’s critical flaw is that they don’t solve a problem with the Surface. In fact, you could argue that the Surface actually causes more problems for users. That’s not a good start for a new product.
I disagree a bit with it not solving a problem, it solves the problem of Microsoft not having a Tablet computer in the marketplace.
