I have been a developer for a long time. I am deciding when to just use Snow Leopard as my primary operating system, now or after it is released to the public. In the past I have always had a separate hard drive for testing, and I keep nuking and reloading with the latest seed.
Now with the current seed (SL), Apple is offering updates via Software Update. I know the final release is scheduled for September, but I think I am ready to reload my new MBP-13 and go all Snow Leopard. It would allow me to more conveniently work on and test my applications and I am going to upgrade the first say out anyway.
What really prevents me is the question, will I have to nuke again to install the final release or can I just do an upgrade?
