This question comparing the beta and daily-live builds of Ubuntu+1, was closed as an exact duplicate of this question, which is a much more general question, "Are daily builds of Ubuntu stable enough for general desktop usage?"
I had asked 3 specific questions (numbered 1,2,3) which only compare beta and daily-live with each other, given that I'm using a pre-release version. They do not ask if I should use a pre-release version to begin with. Therefore I think this was incorrectly closed as duplicate.
