I moved from 7 to 10 and not looking back. Technology changes! Just to stay even you have to change with it. Yes 7 like XP was stable and solid. However those of us that's been around know they didn't start off that way. While 10 is not perfect, it does have some nice features and like XP and 7 it has a good base to build from.
Heck, remember visiting a BBS on a 300 baud modem, then 2400, 9600 and into the internet with speeds that were once unthinkable. Yes I lost some things from 7 to 10. But right now, I'm sticking with 10 and it's potential.
