Assuming I want to upgrade the memory to 4GB and harddrive to 500GB anyway, would I notice a big difference between: a) my current late 2006 Macbook, white 2.0Ghz b) a new late 2008 Macbook, unibody 2.0Ghz Does the newer model have other significant things besides processing power that'll make it faster, etc? I know the video card and design of components can make a big difference, but I'm not sure how much. Also, if I do decide to buy the newer model, I'll probably wait until the release of Snowloepard, if that makes a difference. I'm using it for basic things, but want to use Parallels more and am tired of the drag when I try to use too many apps at once. I also want to play some games like Oblivion and such (nothing too top edge) and possibly hook it up to a large external monitor. I was originally looking at getting the new Mac Mini, but it makes more sense to just use my laptop as a desktop and then having the added portability when I need it. Thoughts?
