It's clearly a product very early in development. I'm surprised Google released such a minimal product in such an important domain, but willing to give it a chance, feed it data and see how it matures.

I'm not -- they need to have some data aggregation/presentation front-end to encourage manufacturers and source-data-feeding app vendors to integrate with the back-end. Once they do that, there'll be more incentive for more presentation front-end work (both by Google and by third-parties -- that's the whole point of an open platform.)
