I guess that is the point. In rally, there is a driver and a co-pilot who reads the legend. But if there was a reliable system based, say, on GPS, maps and current data, that could read the legend as good as the co-pilot then why would you need one?Not really when you consider most ENG situations call for a separate sound op....
I guess it is assumed that an owner of a handheld camcorder will more likely be one man's band than a shoulder cam operator. Still, with prices falling, now there are some who shoot alone with a shoulder cam. I am surprised that the V1 has no built-in mic, but inclusion of the stereo mic on the 560 shows that Sony does its homework.
