My friend just got a 15 in ch pb. Mine pb is two months old, and the specs of both pbs are the same (1.5 ghz, 512 mb ram). I was playing around with the 15 inch pb last night and noticed that it opened programs significantly faster than mine. I had both of em next to each other, and opened different programs at the same time and the 15 inch was almsot twice as fast. I don't understand why. I thought maybe because she has 60 free gigs of hd space on the 15 inch, however I have almost 20 free and that should be more than enough virtual memory. What might be slowing my comp down? Is it just that I have more programs installed? I don't have to many, just the basics as well as office, limewire and bitorrent.
