that I am a hypocrite and I am sorry. I said I was going to not get a new MBP this go round on this forum, but when I went to dinner with Steve and the President, I had a few too many Zimas and Steve put some roofies in my Zima, and then I called up the orderline and bought a new 15 quad core, and proceeded to get every option the guy offered. On a more serious note, I went with the 2.3 GHz SB over the 2.2 as feedback seems to favor the extra 2MB cache when doing tasks such as heavy hitting statistics programs such as SAS (the "computer killer"). A colleague has one and its capability to crunch numbers is unreal versus previous MBPs. I can't say how big the difference is as I have used the 2.2 only a limited amount. I bought it because running SAS and SPSS simultaneously, as I need to do, makes my 13 act like a Pentium I, and the 8GB of RAM gets maxed almost immediately. As i type this, I have less than 1GB of RAM free and only 700 of it is used on the system itself. I may wind up getting 16GB shortly. But yeah, I just ate my own words, and they tasted pretty good.
