I was wondering how apple did the processors when they switched to intel from PPC. I was all ready to buy but since they pushed back the updates till whenever, I am wondering if I should just bite the bullet and get whats currently selling. If they only historically upgraded the top of the line (17", & 15") or like on the Imac the 27" being the only one available in quad core. (I have wondered if the whole line desktop and laptop, might be upgraded to I-core as well) I can potentially wait another week or so, but I am needing to get a couple pretty soon. I am working on an app with my partner, and we are still using Pc's and we can till do some of the graphic files and jut transfer them to mac once we do upgrade, but both of our computers are pretty old (5+) and hopefully any upgrade will help speed up production. My problem is I am fronting the hardware myself, and if It does really boost performance what they are rumored to, I would rather buy new instead of refurbished. But if they are likely to just bump the speed on the core 2's for the 13"s the $400 it would save me on a pair would be a nice discount, if the speed bump is minor, and only the top of the line machines get the I-5's (or whatever they put in them). Should I try and hold off another week or 2? I mean if I do go refurbished I will likely have to buy them one at a time anyway.
