I've never used Windows 8, but I do think that lots of the complaints are from people who haven't bothered to learn a few new things.

Don't get me wrong, I'm no Microsoft apologist. The huge interface change to the Office Suite in 2007 remains a total disaster.

I have to say that I quite like Windows 7, though.

'Switch to Linux' is an easy and somewhat lazy thing to say. Many people don't have the requisite technical knowledge.
