Add my thanks, Dennis, for your willingness to pinch-hit so quickly on this one.
Nice write-up, too, with some tasty tidbits not found in other coverage! I'm also quite interested in Sony's plans to expand their offerings, even though I don't have a Sony model. Competition is good for business.
Same for their plans to improve their store interface, of course.
Regarding the size-of-business issue, big companies are inherently less efficient than small companies with regard to management structure, but usually expect larger margins per sale, partially because their management structures only come in size XXXL. I think both of these factors contribute to their need for much larger volumes than smaller companies.
