I've just bought a new MacBook Pro and I'm not really liking Lion, mainly because of the bland grey look, especially the new Finder and it's sidebar arrangement. As for the other new features I really don't see myself using any of them, which is why I never upgraded my iMac to Lion. So basically I was wondering is it worth the downgrade (not how to do it)? I've heard that SL uses less memory and has better battery life, is this true? Also, if I want/need to come back to Lion at some point in the future will I have to buy it or will the App Store remember that I used to have it? I'm just thinking that since I haven't moved any files over to the MacBook yet if I'm going to downgrade I should do it now.
