Totally agree…
After my experience with Windows 8 and Windows Server 2012, I am now allergic to anything “Metro”. That is coming from a developer that bought Windows Phone 7 when they first came out.
The problem with the Metro is not that it is new, or different. The problem is that it is irrelevant as desktop replacement. It is a UI focused on tablets and touch oriented devices. The bigger the monitor the ugliest it looks and more difficult it is to use.
Microsoft is presenting it as “the future” to catch the attention of developers and herd them towards that direction. Unfortunately they will probably manage to alienate a lot of them.
From a business perspective (in my line of business in particular) all these “new” directions have no value whatsoever and what they have achieved is to demonstrate how irrelevant they can become in the future even for the business. The only thing that keeps them alive (in my field of work) is Excel, everything else is replaceable.
At this point I am waiting for them to either sort out their mess with Windows 9 or else I will have to learn everything from scratch, by moving to Linux.
