+1 for classic shell. However there are some potential advantages with the Win 8 start screen such as building groups of programs, my main beef is the tiles are big and ugly. I wish there was an option to reduce them to icon size.
There is a lot of crap "apps" bundled with it as opposed to "programs" and once you get rid of them things improve. There too much stuff pulling things off the internet all the time. I never understood why you need a special "app" for, say, Facebook when it works perfectly well in your favourite web browser.
Other nastys are things like the PDF reader app, install Acrobat or Foxit or whatever and associate PDFs with that.
The OS itself is very good indeed.
