So I'm currently debating between a new iMac or simply upgrading the MacBook I have now and running it until it craps out on me. It has 2.0 Ghz Intel Core 2 Duo but only 1 GB of RAM, so I was thinking of maxing it out at 4 GB and upgrading to Lion. It's not that there is anything wrong with the laptop...it is just starting to feel a little sluggish. Would bumping up the RAM take care of that? Thanks!
