I completely disagree. I think Amazon.come is absolutely amazing, and I do the vast majority of my shopping through it.
Bezos's intention was to offer everything under the sun when he started the company, hence the name Amazon, because of it's diversity in terms of number of species that exists there.
I compare my experience with Newegg, and although I've bought some stuff from Newegg, I will generally go with Amazon, even if it's a few dollars more expensive, because I trust Amazon so much more, and the entire experience is so much better. I'm basically their model customer, and they have me hook, line, and sinker, especially with Amazon Prime.
Maybe that was his intention, but it's hard to deny that the main focus of Amazon was (and may continue to be) books. I think it just boils down to whether or not you believe in the aforementioned idea that it's only possible to do one thing really well.
