For anyone curious about this topic in the future -
***YOU ARE USING A BETA OPS***
Unless you have a *lot* of experience Beta testing Operating Systems, ***don't*** upgrade. Don't put this as your main OS on a production machine. Don't Think that just because it is being released to the public for *testing* that it is 100% stable.
I cannot stress these points enough. If you play with fire, you have to reasonably expect to get burned, no matter how good you are. If you install a Beta OS, you have to ***reasonably*** expect it to crash or muck up at some point.
If it were bug free, it would not be a Beta.
