What Is Most Annoying
The Metro side can be viewed as an elaborate Start Menu and you can use the Desktop side. That is what I do and it has not been a big issue. I do not even have an appropriate tablet to use it on and I'm okay with it.
I agree that Microsoft is screwing up here because they are ignoring user input on many ground level things. It just seems so conceited and ignorant for them to proceed as they are. I just do not get why they would ignore good suggestions.
The most annoying thing is that I refuse to be part of the Cult of Apple and am stuck with Microsoft's mistakes.
