Query: Annoyingly necessary profit generator for Sony

Works as described. I am just so annoyed that Sony would lure me into buying their video camera for a competitive price without including this cable, making the overall cost of the camera no longer competitive. It's smart for Sony to conduct business this way, but only in order to earn profit in the short term. You can bet I won't be suckered in to buying any more Sony products in the future, now knowing that this is how they run their business.
