The 'problems' come from people trying to use 7 the same way they did XP. It's not the same and cannot be used the same way.
That is true. You have to adapt to its peculiarities but once you do it is worth the effort.
Well some might but it is not a requirement. I have
never liked icons and so always show files as lists, similarly I always have all files and extensions shown. That is not going to change. I also like to have an independent means of doing certain things even if the same can be accomplished within Windows. MS might want to see us doing things their way but they still allow us some leeway so you can't blame some of us for choosing a different way. :)
