I am looking for anecdotal evidence (or even scientific) of the performance of older Macbooks under Mountain Lion. I am debating whether or not to install it on a late 2008 aluminum MacBook w/ 2GB RAM, which Apple suggests is the minimum system requirements. I currently have 10.7 installed on it, and it runs sluggish. If 10.8 performs better, albeit slightly, it might be worth the install. If it is worse, I will probably stick to 10.7. I thought about downgrading to 10.6, but there are some features only accessible in 10.7 that deem keeping it, although it's slow performance, necessary.
