Hey all, I have been thinking about switching to a mac for a few months and am waiting for the new macbooks to come out soon now that I have some money saved up. Right now all I have is a Dell Dimension 4600 PC. It has a Pentium 4 2.4 ghz processor and 1.25 gb or RAM. I am wondering how much of an improvement a new macbook would be, say with a new 2.4ghz processor and 2 gb of ram (which could be what the new macbooks are)? I mean I know the OS is a huge improvement in itself but was just wondering if it will be significantly faster than what I'm used to. Thanks!
