Apple lists Aperture's minimim system requirements as:
- 1.8GHz Power Mac G5, or
- 1.8GHz iMac G5, or
- 1.25GHz PowerBook G4
Which of these Macs doesn't belong?
It's curious that Apple recommends that Aperture run on 1.8GHz G5's and 1.25GHz G4 PowerBooks. I wonder what type of performance penalty PowerBook users will feel when running Aperture? I can't imagine that it will run nearly as well on a G4 PowerBook as it will on any G5 desktop. The problem is that a great many professional photographers that shoot in the field will want to use Aperture with a PowerBook rather than waiting to drag their memory cards back to the studio to download the images.
I hope that Apple makes Aperture perform acceptably on its current (and previous) crop of PowerBooks otherwise they run the risk of releasing a groundbreaking application that isn't usable for most photographers in the field.
