I have a 13 inch aluminum MacBook (late 2008 model) and I recently upgraded to Lion. It simply hasn't been working out. Everything feels very sluggish and I honestly don't really have that big of a need for all the new features. I was planning on downgrading to Snow Leopard, but I also have a Leopard install disk (the one that came with the machine.)
Processor: 2 GHz Intel Core 2 Duo
RAM: 2 GB DDR3
Graphics: NVIDIA GeForce 9400M 256 MB
Will I see much of a performance gain from using Leopard instead of Snow Leopard?
Are there any apps that require Snow Leopard? That simply won't work under Leopard?
