My thoughts on this ...
1. Is Files really that bad? I've used Mac's Finder, so I know how bad things can be
2. Yes! I get to go to the sysadmins at Uni and say 'I told you so!' :-)
3. I'll be sticking with Mint and Cinnamon
Something else occurs to me (that'll probally get me a tonne of down-votes), Unity and W8 Metro were both designed to put the same interface on desktop machines and phones, right? What a stupid idea. I've also heard people say the same things about both UIs; that is, it's not so bad when you get used to it. That's not a good argument.
Perhaps it's just that I'm rapidly approaching middle-age and I don't like radical ideas anymore.
