I just got a new 2011 MBP from my college. It seems to run a lot snappier and faster than my 2008, which has a faster processor and better graphics card. They are both running lion with 4 gigs of ram. Is this to be expected with a more recent model? Or is it just because of the amount of apps and stuff on my 2008? By snappier, I mean start up is super quick and apps launch a lot faster. Apps also don't hang as often as on my 2008. Do you think a clean install on my 2008 will make it more comparable? Thanks.
