I'm pretty dead set on a Macbook Pro, but now I'm wondering if I should wait. Budget is about $2500. Advice? It's been about four years since I bought a new computer. I'll be doing a lot of photo and video editing (Final Cut, Photoshop etc) and I like to watch movies. Not much of a gamer. Is it worth jumping to the 8GB RAM from the 4GB? How far are we from 8GB being the new standard?
