I use Windows 7 on my Mac because I have to to run my accounts prog. Never had a prob with 7 but know a number of people who have had huge problems with 10 and on that basis alone I would wait if I was having to do it, I understand that that might not be an option for you though. On the other hand Mac has served you well since 2008 and if you get another 7 years from your next MacBook that has to be worth thinking about.
