From experience, and once said that I find, like the board skin, the possibility for the final user to change the shell to one of his/her liking a basic freedom, a line needs to be drawn.
I do understand how there is the need for company PC's to have a "same" shell so that as an example workers that use the same machine on subsequent shifts or that move from one workstation to another find themselves in a "same" graphical environment.
Unlike most people that don't like the NCI and that wish the return of the "classic" UI, I find that the NCI, notwithstanding it being an abomination of ugliness and lost functionalities is well within the fair choices of the MS (demented) designers for the new OS's, of course I wish they had made it more easily swappable with something else, but this possibility of changing the shell should be available only to final "single" users or - alternatively - company wide.
What I consider a form of perversion is the sheer idea of a third party of proposing to apply a NCI like interface over an actually good, working and tested one, but much more than that this snippet:
By displaying useful shortcuts such as weather, calendar, news, stocks, and frequently used programs with highly recognizable large icons, WinMetro turns your desktop to a productive work station with fast access to all your programs and files.
send shivers down my spine as all these years I managed to be fairly productive using an accessory called "window" to look outside and see what the weather is, another one called casually wall calendar to see what day it is (even during a blackout) and had no §@ç#ing news and stocks on the desktop to distract me from work.
The app in itself is ok, the message IMHO much less so, something like:
Even if you cannot afford the new Windows 8/8.1 now you can have the same senseless, distracting and offending to the eye UI on your XP/Vista/7. Stop worrying, you can now also reduce your productivity even on good, working versions of the windows OS.
would have been more truthful .
