I never got the windows 10 installer reserve update notification, so I just went to the website to download the OS and it gave me the upgrade tool (~18mb) which worked like a charm.
In about an hour, with less than five or so clicks, it downloaded the OS and upgraded my work laptop to 10. No optical or USB media required, it took care of it all.
The OS is pretty clean and responsive. It does a fantastic job of assembling driver functionality, or at least this was the case on my first test system. Tbh I don't really hate it yet.
