I am curious about the system requirement of Snow Leopard. Since the performance and speed are better on SL, I think Snow Leopard will consume a little bit more resource of our macs., although I know Snow Leopard is just only the refinement of the software. So, my question is that WILL YOU UPGRADE YOUR RAM OF YOUR MAC? P.S. I'm a mac beginner. I know a little thing about mac, so please don't be angry with my limited knowledge. Thanks!!!
