This is actually really true. I started off with a bit of a negative attitude, thinking how can this possibly work as my main computer, etc. etc. But I gave it a try.
Completely surprised myself, I love it! It took a while, I found it hard at first, but I forced myself to learn, and not just install a Start menu program, and now I love it! It is super fast, the start menu is great once initially configured, and I love Windows 8 now I have learned to use it properly.
If I have one thing I would change, it would be the Charms bar. I think it is great, but going to the corner of the screen only to go down again seems a bit inefficient. Keep this method, but I think they should also add a feature where if you scroll on your mouse wheel, and nothing scrollable is selected, then the Charms bar should open, IMO.
I intend to write a small program to try it out.
But I love Windows 8!
