...for doing actual work, rather than faffing around with Metro apps.
In fact, it's less of a mess than Windows 8.1 is and I'll be switching my work PC to it as soon as the volume licensed version becomes available. I've been running the previews on my home PC and laptop since October and going back to Windows 8.1 at work is like a kick in the teeth each morning.
Games work just fine btw.
Note that this relates to traditional desktop/laptop use. I don't know whether it'd be any good on tablets but frankly I don't care - can't stand the things!
