This brings up some questions.
On a 35mm camera a 85-105mm lens is considered a portrait lens because it
keeps people noses smaller than a 50mm up close.
Now say a 55mm lens on a 1.6x camera (APS-C) equal 88mm. Is the
88mm lens a portrait lens or do you get a big nose because it is really a
55mm lens?
If the full frame sensor has the same number of pixels as the APS
is there much difference
in performance. Larger pixel are suppose to pick up less noise and
may work faster(?) but is this a sufficient increase in quality to be work the
extra dollars?
I know your example was picked to illuminate the cropping factor. If
you were shooting an APS size sensor on one camera for the picture wouldn't
you crang up the zoom on the 5D to get the same picture

It isn't a multiplication factor. The 1.6 to 1 is a reference for us to better visualize what will appear in the viewfinder. What it really is though is a crop factor. You can get the same photo with the 5D as you can with any APS sized sensor just by cropping. The 5D just captures information the APS sensor doesn't. Now does that require post processing? You bet. Does it slow the camera down to capture information you might just throw away later? Probably at times. Does it make it harder for you to visualize what the final print will be? Possibly and if it works for you great. But you really aren't getting extra focal length, just cropping. Now will full frame lenses sometimes you are working more with the center of the lens which can improve some lenses. Some lenses designed for full frame don't work as well with APS and other that are designed for APS won't work at all with full frame. Need a new ride?
