So I am finally switching from Windows XP to OS X for recording and mixing and have decided on a 13" Macbook Pro because I do a lot of mobile recordings and really like the portability, plus I already have a 24" monitor I hook up to at home. My 1.83 gHZ Dell with 1 GB of ram was able to record at least 10 tracks at 24 / 44.1 easily, and mix 24 tracks at 24 / 44.1 with my MOTU 828 mk II hooked up to it. I tend to use a good amount of Waves plugins and convolution reverbs. Whichever Macbook Pro I get, I already have 4 GB of ram and a 7200 rpm drive I would put in. Will I be able to do all this with the 2.26 Macbook, or am I going to need to get the 2.53?
