Re: Those of us who haven't "upgraded"
Hmm, you've clearly not used it. IMO Win8 is an improvement on 7 with the caveat that you need to spend an afternoon sorting out the start screen (uninstall the crApps, create logical groups for your daily driver software etc) and learning some keyboard shortcuts (irony!). Use is exclusively on a multi-monitor desktop machine, no touch screens. It handles multiple desktops better than Win7 too.
Now, I prefer it to the restricted Win7 start menu design. I realise I'm in a tiny minority here tho ;-)
I will move to Win10 soon at work so I can test out all our software with it, but it looks like they've adopted a 'worst of both worlds' approach to some of the UI :-(
I'm with you all the way on the 'flat design' shite though...
