It's fair to call out Thurrott, but if you want to do so, you should try to at least rise above his level.
Sure, Microsoft tried to build lots of tablets without copying anyone. How did that go?
Edit: To be fair, I'm just reviewing Microsoft's old OLAP invention MDX, since I might want to suggest using it as part of a solution (in a different problem domain). So far, it seems quite neat (I have only read, yet).
Mind you, I don't see it as a problem that Apple and Microsoft have both by and large profited from imitation, as that's what drives the industry forward. Someone has a good idea, and builds it on top of an established base of other good ideas, imitated from others. Standing on the shoulders of giants, so to speak. What I mind are the contortions of historical revisionism one has to go through to paint this picture of "Apple innovates, Microsoft imitates."
