Do you realize you just told me what I told you? Majority just OWN a blue ray player - they aren't encoding their own. In fact, I can think of two major users of blue ray encoding. Small scale professionals which can't be a large user base. The second is pirates. And even these are abandoning Blue Ray in lieu of hard disk storage, so blue ray becoming common is arguable at best. I already have no need for blue rays ever - my PC streams full HD content to my HDTV with no need for physical media - and THAT my friend is the future. Physical storage in 24 months will be irrelevant. I mean common. Straight economics here. Buy an expensive blue ray burner and keep paying to feed it disks, which I then need to store and cataloge. OR I keep all my movies and media on a 2TB drive which cost less then the BR burner to begin with.
You provide raw statistics with no thought as to their possible meaning, followed by your own speculation, so please, lets stop with the pot calling the kettle black. The POINT is, as you've agreed to with your own little tid bit is that most users are not using their computers for video encoding or digital content creation - which is what quad cores are really good for. The other 80 percent of us or so will get all we need from a dual core.
The small portion of us that are gamers couldn't care less about quad cores - we want max frame rates and quick load times. THat means fast, overclocked CPUS. Which is why I am excited about an i7 dual core, which I will be able to push much further then I would a quad core due to heat issues.
