I'm on a 1st gen. Macbook (core duo) and cloned my tiger install on an external usb drive.
I'm about to install leopard (I wanted to wait until I had the $ and at least a 10.5.1 to come out, which there is now, and even a 10.5.2 coming soon).
I have used the SuperDuper! app to clone my tiger installation and my question is:
Which is better: the archive and install option or clean install with migration assistant of the cloned tiger installation?
