I'm considering a new 15" pb. I do mostly web development and graphic design with some video editing tossed in for good measure (mostly short form). Will 512MB RAM generally be acceptable? (I know mileage may vary) I don't usually work with graphics files larger than a few MB (other than video). Also, can apple memory coexist happily with 3rd party memory? I was thinking of getting the powerbook with the single 512 chip ($90 extra educational) and adding another 512 if needed in the future, as this would save money in the long run ($90 for single 512 + $140 for another 512 vs. 2 512's at $140 ea.).
Thanks for any input you may have.
