I bought my 2.2 macbook a couple weeks ago, plenty of speed for me. This being my first mac I became upset when only one week after my months of saving for this purchase..BOOM new model.
BUT..My friend just got a 2.4 macbook yesterday and we were doing some side by side comparisons. We couldn't find any differences other than maybe a second or two opening apps (highly scientific tests mind you
. And this is with an increase of .2, you'll be getting just .1 Ghz
Anyway, be happy with what you got. After reading these forums for the last few months I've realized that my machine will do more that I will ever need. Just my two cents.
