The main thing to keep in mind, as with all Windows versions .. Microsoft will end updates and support, I believe in a couple years for WIN7 .. so, any way you slice it, WIN10 is in most folks future, whether they like it or not ..
I was an early adopter of the WIN10 free upgrade on more than one machine, and for me, it's been great .. 10 runs smoother, it runs my old software going back to XP very well, I have had no security issues, it can be tweaked in so many different ways .. my history with a PC goes back to MSDOS, and then to Windows 1.0 ..
