I think that great startups make you go, "wow. that's much better than the old way." Having spent a decent chunk of my undergraduate education (electrical engineering at the UW) looking up datasheets for electronics components, I have to say that this is 100 times better than Googling.
I don't think most people will get it. After all you need to know you're looking for an LM348N chip. But you're immersed in that world, then its a perfect startup. They should be wildly successful if they can figure out how to market their product.
