the cola war explained demographically?

I just read an essay, Why the Super-Rich Only Drink Coke, by Jamie Johnson on the Vanity Fair page. Essentially, the conclusion is based upon the associations and manifestations of the brand identity. But I think everyone can appreciate a little nostalgia. Who wouldn't prefer a Coke in a bottle to a Pepsi in a can? The only time I ever require either is with a healthy dose of rum mixed in, so I can't say I have too much of an opinion at that point, anyway. It just goes to show the signifigance and value of a strong branding strategy and maintenance of target market relationships.
