That's precisely my thought. Keeping software up to date is a great thing, but I also need a good level of stability. And so, having the easy update rollback is a fantastic thing.
I used to play with like the Ubuntu beta versions, but I would always play with them inside of virtual machines while leaving my hardware on something that was stable.
And I play with beta software on my phone all the time, but that's at the application level, not the operating system level.
