I am hoping to get the public beta invite but I had a couple questions. 1) Can you dual boot your current OS X and the new OS X beta using bootcamp or another method? 2) If dual booting is not an option, if you upgrade your current OS X do you have to reinstall completely when the final comes out? I installed the Windows 8.1 public preview when it was released and ended up having to reinstall everything once it came out officially. Really don't want to have to do that again, I will be in the dog house for sure this time Thanks.
