Well if you take the original quote in the context of the last three to five years, it is indeed un-Apple-like.
Apple has recently redesigned every computer they have except for the Mac Pro, which hasn't been significantly redesigned in something like a decade.
Call me old school, but I would rather have a bigger chassis with internal expansion than the "small for the sake of being small" design of the new Mac Pro. In my opinion, having external devices (requiring their own power cables) creating clutter around the new Mac Pro somewhat nullifies the advantage of its tiny footprint.
