Desktop != Tablet != Smartphone
They wanted to create the same experience for the various platforms : fail....
They made MAJOR changes to a very functional OS ( XP , W7) rather than taking small steps = fail.
The expect that users will forget 10-15 years of habits and instantly move over to a new paradigm = fail.
All they had to do was move in small steps, test the water and either implement or remove...
Now they are in a position that they need to make new radical changes in order that the userbase falls back in love... but that is not going to happen overnight.
The tablet world is not the proffessional world is not the smartphone world... Different userbases, requirements and situations. MS Please, please, please stop confusing them, I can easily handle the differences between the three, they really don't need to have the same interface..
