Did anyone see the benchamrks just posted at Maccentral? Very little differences between 1.5 and 1.67 Ghz. - a few seconds at best in most cases. I guess it is different than when the 12" was 1 ghz and the 17 " was 1.33 (a 33% difference), compared to now. Doesn't this mean that really the best value is the 1.5 ghz 15" PB or even the 12" (if yoiu don't want an ibook that is).... I guess also the uniformity of the 5400 HD makes a difference.... Comments anyone? Esepcially for us PB potential buyers... I guess the REAL advance will be dual core G4 to get improved performance... Hell, it seems that a dual MDD PM is better than a single 1.6 G5!!
