Thanks for the feedback. I tend to agree with you about the fact that the analytics and backups offered are not new, but the accessibility to designers is, and I'm glad that you pointed it out more explicitly than I have -- especially given your experience.
I also think that in some ways, the 'usability' of each technology is the big hurdle that must first be cleared before "marketing" becomes the key differentiator. I approached this with the thought that among the existing (or discussed) technologies, any improvement in the technology or functionality is, at best, incremental. That, along with some other factors, is why I suggested that marketing would represent the key differentiator. Glad to hear other thoughts on that, too.
