Keeping in mind that media hypes up anything they can represent as "controversial" or attempt a "train-wreck" kind of slow drive-by by rubberneckers to read their articles/blog posts.  In other words, out of a dozen "journalists", maybe one or two spent more than 15 minutes on Windows 8, have never tried anything other than Windows XP and maybe 7 (which are very similar to each other in my opinion) or started in with the mind-set of "this is going to suck, I just need to find details...".

I did not say, however, that Windows 8 is any good (or bad).  

Personally, I have gone through some UI changes on the Linux front (Gnome2, Gnome -shell, Unity, KDE, Xfce, etc.) and the one thing I have gathered from this is that you cannot go into a new interface and expect it to run just like the other interfaces.  It's a mind-set that most people haven't had to use because Windows has predominantly stayed the same in a UI manner since 95!

So Microsoft is starting something new, a new UI and a new "philosophy" of how to navigate the system. This after waking up and realizing the world has gone on without them and IE 6 is no longer the only browser in the market (let alone Office, Windows Server, etc.).  It's taken a while for them to rub the sand out of their eyes, and I think they are still working on their first cup of coffee but at least they are shambling around like a Monday morning zombie.

The OEMs, though, are grumbling and whining about having to change their way of thinking, to include touch, mobile devices, power AND efficiency and more device-like computers than the old beige boxes sitting on a desktop.  Coupled with strong Apple sales and a slower economy to navigate through and they have had to actually... um... work!  Innovate!  Come up with something more than same-old-same-old.  And just to help drive home the point, now they have to compete with Microsoft themselves!  Gosh, guess they can't be caught sleeping at the wheel anymore.

Microsoft "rebooting" Windows 8 does make some sense.  The name "Vista" became synonymous with "sucks" and though it was more of a bug-fix and polishing up of Vista, "Windows 7" has become the heir of Windows XP's mantle of being the most popular operating system (of the world).  

Technical issues will exist regardless of how long they tested and developed the OS, especially at the size and and magnitude Microsoft and Windows exist. Really what Microsoft needs is a marketing "reboot", not a technical one!

Hopefully they have learned.  They have had 3+ months of real-world feedback that they could address so that Windows 8 Pro on Surface can benefit from it and have fewer flaws.  The world has had 3+ months to learn how to operate this new UI.

I think that Microsoft needs to push the education (books, video, blogs, etc.) on HOW to work the Windows 8 interface and push the deals to get it into the hands of people so they can get used to the new interface.  Also, there are plenty of improvements "under the hood", let people know how it benefits them whether it be safety, security, stability or even putting into place a framework that can easily handle massive changes in the near future.

Now is their time to push and push hard on it; Apple is looking old, Linux's competition is still young and the mobile market is young enough that nothing is set in stone.  

Yet.
