Isn't Windows 7 in a large way a refinement of Vista where they did get the "details" right? It's probably overkill to say that Microsoft never gets the details right, but I do agree that their first version product which introduces their inovations is generally rough and unpolished to say the least.

I loved metro when I first saw the build videos in 2011, but that's because I looked at the demo apps as early and unfinished examples of the direction they were taking. Now over a year later I see almost nothing has changed and the same level of quality I saw back then is what is being released now. A lot of things are unintuitive, apps have awkward layouts, the icons are downright awful, etc.

There was a lot of promise for Windows 8 back then, and to some extent I still expect them to refine the UI and make it into a better user experience by the next version of Windows -- but by then the feeling of "innovation" will be gone and they will have missed their chance to make the big impact that they needed and would have otherwise gotten.
