Hi, I'm thinking of getting windows to play some steam games and have it just in case I ever need access to windows software. What OS should I be looking at getting though? 7 is cheaper (£50ish), but older, and seems to be discontinued with any new macs in bootcamp. 8.1 is twice the price of 7 (£100) but seems to have had a lot of bad reviews over the interface and 10 is not out yet, but is apparently subscription based (which I'd rather avoid!). Is that accurate? Are there any other known issues with running bootcamp with these? Thanks!
