We appreciate comments like the above much more. It promotes better discussion.

Regarding the content of what you said, we still disagree. I know many people who use MacBooks, most of which are CS researchers and one astrophysicist. Of that set, I know of one person who upgraded their machine at all (a CS professor who replaced his harddrive with an SSD). I view Apple's design decision of making the RAM non-upgradable in line with my use, and the use of almost everyone I know. We certainly try to do work that has value, and we do not see our work computers as fashion accessories or trinkets.
