My main partition of about 445gb runs 10.8 Mountain Lion, which runs much better than 10.7 Lion and I think better than Snow Leopard, too. If your Mac can run Lion but can't run Mountain Lion, you should run Snow Leopard unless you need something specific in Lion that Snow Leopard can't do; I never like Lion much. But if your Mac can run Mountain Lion, there's almost no reason not to do so as your main OS unless you absolutely need Rosetta frequently.

But I can definitely vouch for the external hard drive installation method. I've done it before a few times with older versions of OSX.

My reading of the Apple licence agreement is that I could legally install Snow Leopard in a VM on Mountain Lion while I still have Snow Leopard on this machine. If I needed to run it more often I would try this.

A senior Apple Tech person told me Snow Leopard cannot be installed on my laptop due to hardware limitations. He said there are 3 options: 1) VM ware solutions - create a partition and emulate older hardware; 2) Buy an older computer that can run Snow Leopard; and 3) run SL on an external USB hard drive. I have not done any of this yet and am very interested in hearing more success stories.
