Actually, Windows 7 was vista 2.0!
Actually, it wasn't. It was and is Windows 7. Vista 2.0 really does not exist. It was a metaphor for a failure by design.
Windows 8 is a forced blending of incompatible elements such that both the touch and mouse/keyboard interface is broken and incomplete. It is especially so for the people who actually use their computers to do work rather than simply consume content produced by others. If all you want to do one thing at at time and run apps, tweet, email or brows the web, Metro is sort of OK. However, if you want to be productive, use more than one window at a time, and produce complex content then you must constantly fight having to go through the butt. ugly, totally useless, and unnecessary Metro screen.
It would have been trivially easy for Microsoft to have done it right. One way would have been to have a touch centric OS and a mouse/keyboard centric OS (ie. Windows 7). The other way would be to provide the user with a choice of touch or mouse/keyboard centric operation. As it is, the people they are relying on to provide content are constantly having to switch contexts between two incompatible universes to get much of anything done. Each context switch will result in a significant fraction of an hour of lost productivity because of focus being broken. Staying in "the zone" is very important.
I have 70 applications that I must use to service the various tasks I must perform to develop content: software, websites, documentation and the like as well as remote technical support and system and software diagnostics. Try pinning that many icons on the task bar and the task bar would be useless. Then there are many more applications that I must use infrequently. You see, I have real work to accomplish and I need to do it MY WAY and not the way some brain dead manager at Microsoft insists I must do it. Personally, I couldn't care less about what Microsoft managers want. They can go suck rocks for all I care.
I understand that Microsoft doesn't give a damn about the people who must do real work. They are interested only in finding a way to build a new cash cow by having a totally captive audience brainlessly buying apps from THEIR app store. They also want have a way to push paid for advertizing out to that "customer" base and they think Metro is it. That is their choice. They are so focused on creating that cash cow that it is clear that they haven't thought about where all those apps will come from. They are building a cash cow that won't give cash without the apps.
I don't have to like it but I must somehow find a way to live with it or stop working and stop being productive. For now, that means shunning Windows 8 and staying with Windows 7 for as long as possible.
