If you're fond of Linux Mint Cinnamon, then Windows 10 is not that bad at all. The start button and menu are very similar indeed.
Perhaps the Redmond designers had a very close look at the open source alternatives here. Windows 10 is very fast indeed when it comes to installing and removing programmes. If you get a version without too much bloat- and nagware it could be usefull.
I've had my reservations towards Microsoft and Windows for years and years. However this version is promising indeed.
