A few more thoughts on VHS vs. DVD vs Blu Ray
I appreciate the author's point of view, and generally agree. However, DVD vs. VHS has, I think, a few more components to it. DVDs often have better picture quality than VHS, generally due to the technology (tape wear and dirty heads tend to degrade picture and, sometimes, audio quality). DVDs are more compact, making it easier to store. Their size is the same as CDs, so they "fit" better into cabinets and the like. All these factors played into the consumers choice of DVD vs. VHS.
This "choice," however, was ultimately driven by manufacturers, with DVDs offering them far more options for advertising and branding, content (due to additional capacity vs VHS) and control (DVDs that force viewing of certain portions). Consumers did not fight the evolution to DVD, so it happened.
As a simplistic non-engineer, I always thought Blu Ray vs. HD DVD was a simple choice in favor of Blu Ray, and I base that on capacity. That is overly simplistic, as cost of disk production and other factors certainly influence the choice. Ultimately, though, the "winner," if indeed either of these two win, will be driven more by manufacturer influence than consumers, if the past is any indication. My preference - get all of my content onto one small, portable, easily backed-up "thing," whether it be a disk, cube, or magic crystal. Oh, and I'd like a time machine, too.
As for me, I'm with the author's friend. I am sticking with my DVD player, whose video and audio quality is quite good over my HDTV. Then again, I may have been the last person on my block to go from VHS to DVD, so I am not exactly a bellweather for technology shifts.
