Just curious about the speed.


I am, this is my first MB but it's lightning fast compared to similar models in the Apple Store with 2GB RAM. It never has to swap to the HD and most apps remain in memory so it's almost instant.
 
I am running with 4 gigs.

Speed is significantly faster than my previous MBP with 2gigs of ram.

It is hard to say what exactly makes the difference, there are many new improvements on these new ones in comparison the the 2.33ghz, 160hd, 2gigs ram I had before.

Application opening: much faster
Boot time: much faster

The entire feel seems smoother to me, but then it also felt much smoother on the last gen MBPs in comparison to mine (gen 2) so it is hard to tell.

Depending on what you have now, you may notice a significant difference or you may not. In comparison to my wife's 1.83 ghz white MB with 2 gigs of ram in it, it seems snappier, smoother, more responsive and far more capable of running taxing "tasks" i.e. Spore.
