Everybody had drivers ready to go except creative Labs (of course - when do they ever update anything on time). The sound still works with the built-in drivers though so whatever.
I ran Edge once, saw that it had no adblock available and dumped it.
The new calculator app sucks.
So far no problems running anything. It took about an hour to set up the new start menu the way I wanted it. I unpinned all the crap they give you and then pinned all the thing I use in nice categories. This setup lets me have a clean desktop.
The new virtual desktops are nice. Flat interface is growing on me.
MS still has a dumb UI consistency in that they want the preferences setup menu to not just be part of the regular control panel.
I turned all the questionable privacy invading stuff off, including Cortana (which I'll never use). I think 99% of the stuff I turned off is for people who like tablets and/or have only ever used tablets. I guess there will be a lot of those people going forward.
