It'd only be a key question if one assumes the technology isn't going to radically improve over the next 5 or 10 years. It's going to. Deploying to consumers and dealing with such problems, learning from how millions of people use something, is a requirement of that process of improvement. It's similar to people questioning the GUI in the very early days of the PC, because working directly with text operating systems was still superior. It was extremely widely argued that GUIs were junk, were never going to catch on, were too slow, too glitchy, didn't add enough value etc - it's an obvious and common failure to look beyond the tip of one's own nose.
