This is the same silly stuff I hear between Pro and consumer DSLRs. Part of the marketing is too sell higher-end stuff to folks who really don't need it. It works very well as a majority of people could work happily with a 4GB Air (many do), but think they need a 2500 dollar "pro" machine.
These are the same folks who are imagining that they need 32GB.

This is all I was trying to get at from the beginning. Agreed.
