While it would be nice to have more competition in the space, the fact is that we trust Amazon with our bits now. There are other players we could trust, but none with the sheer power of Amazon. Sure they go down once or twice a year, but hey, who among us can claim that nothing in our entire infrastructures never ever goes down? Why would the submitter think that any other current player can keep their service growing and have the same reasonable uptimes that Amazon does? Here in the real world, we don't mind paying for crap that works. That's what makes economies run.
