Has anyone found that a 2,1 running Lion runs faster after upgrading the RAM to 2x2gb (with a limit of 3gb)? 2gb is the minimum for 10.7 and is the only spec I can raise, so is it worth the cost? I currently have 2gb ram fyi. It runs ok and I can play Minecraft and use iMovie and etc, but it is slower than it was with 10.6. But I love the convenience of iCloud and don't want to switch back to 10.6 and lose it. I don't know if the RAM is a major cause of the slowdown from 10.6 to 10.7, but as I said its the only variable I have any control over. Any anecdotes re: this topic will be appreciated. Thanks.
