Not that I'm in the market--I'm happy with my Macbook which I upgraded to 2GB myself. But the problem is people who upgrade their own comps from 1GB to 2GB won't have anyone to sell the two spare 512MB sticks to since the base model already comes with 2 512's. What a waste of RAM.
Can the MacBook run with only one RAM module? If so, Apple, should offer that option at some "reasonable" price above the 2 512 model. Would running on only one 1GB module decrease performance below the 2 512's?
