i wouldn't even count on amazon to exist for that much longer.
they are trading with a P/E ratio of 535 (

Amazon is good at raising dollars though. I remember when they started, it was YEARS before they ever broke even. "making money" does not seem to be as important as moving volume and marketshare to the holders. They have a few things coming that could make a huge difference in the physical and digital goods categories.
i don't care if they invent skynet, there is no way they are going to be making 35 times more money which is what they need to do in order to get a P/E of at least 15.
