I am going to the Apple Store in my local mall tomorrow night to buy a new MBP. With the recent update, I was trying to figure out whether or not I should by the 2.4Ghz/4GB RAM or the 2.6Ghz/4GB RAMfor the extra $250. What is the opinion of any veteran Macbook or General Apple users on this? Is the 250 better spent on the extra speed bump (WILL I EVEN NOTICE THE DIFFERENCE?) or on something else that I could get with the system (iPod, Printer, etc). I am going in with a friend who is a student at a local college so I can get the $200 discount Please help, I don't want to sink $250 into this for absolutely nothing!
