I agree with you...
I only have 1GB on my 17" and find that more than adequate.
If you read my original post you will see that I have already said that 1GB is ample, 2GB is overkill.
Before I started using my G5 with 4GB of ram,
, I got on just fine with my 17" and still do.
I have editted professional video productions and worked on multiple maximum resolution still images from 5 Megapixel cameras for magasine articles without any problems... However, I certainly would never have a machine with less than a GB when running OS X. The difference in performance below that 1GB barrier is stunning!
