3.0 GHz Quad Mac Pro (first generation) with 8 GB RAM, 4 500GB HD to handle the heavy lifting of digital imaging post-processing and storage. I use Photo Mechanic to quickly review and choose good images, discard poor images, then move on to Aperture to post-process the good ones. When something needs more attention or I want to experiment, I take it on into CS3 Photoshop.
Also have a 15" MBP and a 17" MBP. Up until now the 15" MBP has been the traveling machine and the 17" MBP has been a desktop replacement hooked up to a 23" ACD. I also have a G5 rev B iMac (which was my very first Mac!) in the master bedroom, and that is the computer I've been using after 10:00 at night so that I don't disturb my downstairs neighbor, whose bedroom is right beneath my living room (and my computer workstations).
With the recent purchase of the 1.8 SSD MacBook Air, things have changed. I haven't been using the old G5 in the bedroom -- instead I'm sitting in here using the MBA, comfortably positioned with it on my lap, sprawled in a chair, feet up on the bed..... The MBA will definitely be replacing the 15" MBP as my traveling machine and I guess it will also be replacing the G5 as my "after-10:00 PM" machine as well! 😀
