Installed it on my two Surface Pro 3's yesterday.
Yes, it is very nice and they have fixed a lot of annoying things from both Windows 7 and 8.
Always hated it when I would click on a directory and the directory would scroll somewhere off the screen.
That's fixed.
I run multiple monitors. Always been a problem with scaling between the monitors for clearest type. That's fixed.
Also with multiple monitors, you can stack one above or below the other and have the cursor move between them going up or down.
Also fixed the problem of waking from sleep and having the monitors reconfigured on their own.
Finding and adjusting any setting is so much easier now that control panel and a redundant settings box are both a right click away.
I had a problem after upgrading to 10 with AVG blocking Windows Mail from accessing my gmail account. Had to set the firewall to allow the Windows Mail executable to pass thru. Something for AVG to fix.
Had a problem with the new installation not finding my wi-if signal. I told it to continue installing, then rebooted and it was fine.
You're smart to wait and let the bugs get worked out but in this case I don't think you'll have a problem diving right in. They seemed to focus on getting everything right instead of trying to dazzle you with new games and gimmicks. It's miles ahead of whatever you're using now (windows-wise) so go for it.
