I think providing supports to regular consumers may not have been in their dna, but I've been using the business chat/phone/email support through Google Apps, and they have always been top notch. While their answers weren't always what I wanted to hear, that was because of Google policy, versus the reps themselves. Most all of which have been very knowledgeable and human over the years versus most all of the other support channels I've used for companies other than Apple of course. However, there is an enormous amount of more consumers than business customers, so no idea how that support will scale, and if the consumers will get the same level of expertise as business but will be interesting to find out.
The cost of support has to come from somewhere -- is either Amazon or Google generally cheaper for cloud computing? (I know ~nothing in this area). I could definitely imagine a market for both a cheaper service that's lacking support and a more expensive one that offers increased support.
With that said, with Amazon's efficiency in logistics, I could definitely imagine them implementing support at a negligible cost.
