To be honest I quite like the idea of yearly updates. If they are free or dirt cheap than even better! As long as the option is there and doesn't force people to update if they don't want to. If people are happy with the OS they currently have then they can keep it, but for those of us who who like to have the latest system with new features or whatever then great. I see it to be a little like Android, as I love updating and playing around with the new releases when they come.
