Let's say I wanted to start fresh again and install Lion DP4 on my macbook now. And then I do that update that just came out today. When the Gold version comes out, will it prompt me to update to the full version or will I need to buy the version on the mac store and re install the whole thing again? Basically what I am asking is should I wait the next three weeks or so until the full version comes out or can I start early and install DP4 now and then update as soon as it comes out with no hassle? I ask this now because my macbook is running slow and I feel like just starting fresh and I have time to do this now but I want an honest opinion. Should I wait or what?
