All this said, it certainly isn't nearly as large a leap as VHS to DVD. Not even in the same ballpark. The reason the DVD upgrade from VHS was so necessary was that it also increased efficiency of space and shipping, and the functionality and controls of watching a movie.
Blu-Ray has none of these advantages. Also, considering you need a >42"(the most popular size if I'm not mistaken) TV to even tell the difference between a 25 dollar upscaling Samsung DVD player and a 199 Sony BR player, and you can assume that most of the BR early adopters are either PS3 gamers, videophiles, falsely informed, or bought their BR players as status symbols.
Sony has done a great job of forcing this format upon the casual public. The differences seem minute. I can certainly tell the difference, but my parents couldn't. The reality is that the difference just isn't that huge. There is no other functional difference, unless you count extra content....which is usually some crappy free movie game that you play with your BR remote, which succeeds in giving shovelware a bad name.
I don't need your console war.
It feeds the rich while it buries the poor.
You're power hungry, spinnin' stories, and bein' graphics whores.
I don't need your console war.
NO NO, NO NO NO.
