May I ask what you've seen in 8.1 that you didn't in 8, that has almost swayed you? Personally, I still see nothing in 8/8.1 that has even remotely swayed me to leave Windows 7.
Surely not the start button?!
It's probably just more the fact that I'm either getting older, or I've gotten over myself about it and have begun to fall in line
To this point I haven't demoed 8.1, only seen screenshots and youtube videos, but for some reason I cannot explain, it's beginning to appeal to me.
