In a year or two's time, the specs of the MacBooks are going to be better and make those machines look like the dinosaurs they are. The work that most of us do, however, remains unchanged. Sooner or later, even the Mac Minis will outpace many of the machines used in many production places at the mo.
I have to admit that this is something I've wondered about over recent years ... how much of the processor horsepower is actually needed and how much of it just people increasing the specs of a job because they can thanks to the improved processor horsepower.
Newsflash for the Braniac who sent in an A1 display poster artwork at 1200dpi ... no-one is going to stand closer to this job than 3 feet. It's going to get printed at about 75lpi, so 300dpi would have been overkill.
Likewise the A4 Illustrator EPS that arrived with a CMYK TIFF image watermarked in the b/g. Couldn't work out why the file behaved so sluggishly, until we opened the watermark in Photoshop. 2800dpi.
Nobody ... let me say that again ... nobody will be able to tell the difference between your finished, printed image at 300dpi, 600dpi, 1200dpi. Just because your scanner goes up to 1200dpi doesn't mean you have to use it! Fine - use the higher resolutions to extract extra detail if you need to enlarge from the original size, but for output ...? Fer chrissake, can we stop with the resolution machismo, already?
And ... to vaguely return to the point that prompted this rant - a MacBook running CS3 will happily deal with 300dpi and 600dpi images up to a fair old size. Anyone who tells you need higher res than that, well, see above.
Cheers!
