I too also felt that file manager was superior to explorer, so much so that when using Win 95(came with my PC) I would go out of the way to use it.
It will be interesting to see what the natural progression for the current Win 8 UI will be. I am not entirely convinced that we will be stroking our desktops any time soon. Imagine having to do that at work, and if other people had been stroking your desktop as well.
Could cause a flu epidemic.
I am 'upgrading' to Win 8 this weekend, the pessimistic part of me went and bought the Thinix desktop gadget in advance...
