Looking at another thread on this board discussing Geekbench results, I went to Geekbench and searched through some old results of the Macbook 2.4Ghz with 2GB of RAM, new new one, and the new 2.0Ghz Macbook. Here is the summary: Old Macbook 2.4Ghz ($1099 refurbished, black): Average of 3100 (+/- 50) New Macbook 2.4Ghz ($1600) Average of 3100 (+100 / -50) New Macbook 2.0Ghz ($1300) Average of 2700 (+50 / -25) Basically, around 15% performance gain for the 2.4Ghz (at a 23% price premium, that may even out when you take into account the larger hard drive and backlit keyboard). Also, based on these numbers, it seems that 3D graphics performance is not a big part of the Geekbench test. Maybe I'm wrong. I am still going back and forth between a refurb blackbook and the 2.0 macbook. I'll see it on person this weekend and see if the non-performance features make it worth the extra money.
