Looking a lot better than 8/8.1 so far, and the cloud crap (OneDrive, M$ linked settings, etc) looks mostly avoidable if you use a local or private domain account. Kudos to them for un-hiding the local account option as well!

I'll give it 6-9 months before I switch on any computer I regularly use to see how real world stability, updating, etc go. But it seems more of an evolution of Windows 7 in the desktop, with a lot of the irritating aspects of 8/8.1 de-emphasized.

EDIT: the adware that comes with a recent update, which uses 3 MB of RAM just to say "reserve your copy of Windows 10 now" is just f**king obnoxious.
