im not really computer knowledgeable so i apologize in advance but I have a netbook with 1.6Ghz and 2gb ram that runs like a snail...I know the ram is little but it starts lagging after 5+ tabs are open which is ridiculous. I know the CPU itself is a new generation, but why is 1.8? How come it cant be 2.4ghz like the MBP? thanks!
