Things seem pretty clear imho. Home for home users, Pro for SMB, Enterprise, well you get the picture.
I have absolutely nothing against win8/8.1, became user since day 1 and never looked back. Have been testing Win10 for quite some time and have mixed feelings about it. I do like a few things, trying to get used to others (like win98 to winXP, XP to 7, 7 to 8 and now 8 to 10)..
Those sticking with win7, have fun with it, your choice, but DX12, app sandboxing, a 10s boot, a sensational stylist desktop and Edge (I'm intrigued by it and quite impressed) are deal breakers for me. I simply love Onedrive integration and the fact that I can have my desktop, favorites, history and documents virtually in any win8, win10 machine I log in.
Those win7 extremists, give it a try, at least the disappoint won't be as big as with win8 and in this case, will be for free.
