Personally I'd never install a beta OS on my main computer. I use it everyday for several hours. Don't want to takes any chance to mess up the OS and have to re-install everything, especially when I have a lot of stuff in it. Testing a beta on a phone is one thing (easier to just erase and re-install) , but testing a beta on a main computer, even if its late in the beta cycle can be a nightmare and you'll never know when it could happen.
The tiny new features added isn't worth it as well.
