So far, Windows 10 is probably my favourite OS of all time. Rock-solid stable, keeps everything you need at your fingertips. I work faster in it than anything that's come before. I find going back to OSX on occasion really, really frustrating.
This is the first time I've ever heard this. I dual boot Yosemite and 8.1, and hopping over to 8.1 is maddening only for all the little things. No column view, really strange selection behavior (strange to me at least), 5 different versions of a save/open dialogue, and many other things. But you're saying that with 10, you feel right at home? Obviously this is not turning into a windows vs os x debate, I really am interested in the windows 10 experience.
