Consoles are not just for video game since PS2.
Yeah, technology progresses. Imagine that! That however doesn't mean there should be cable tuners (multiple!), crypto card slots and DVR functionality built into a console. That's not a direct path of progression for console technology, that would be branching off onto a sidetrack towards a market that's frankly destined for extinction (meaning: traditional passive TV watching.)
And having additional hardware/functionality didn't deter anyone from buying mobile phones, tablets and so on.
No, because adding those features made sense. This does not. It just complicates things for MS, and quite frankly for cable distributers as well whom would not benefit by this scheme at all. It also makes the console more costly (and likely by quite a bit.)
The time of mono-function devices is over.
Yeah, your stove is SO out of fashion... All you can do with it is cook food!
Seriously though... That which you just wrote is merely handwavy noise. It doesn't actually mean anything in the real world, there's plenty devices out there that don't do more than one thing. Your printer is typically not also a document shredder (although in the case of my aging laser printer, that's debatable...), your router isn't also a fax (shit, I'm really showing my age here! Who here's faxed anything in the last decade?
), and so on.
I think MS wants to release the ideal entertainment machine and surely they can't do that if all the Xbox can do is video games.
There's no such thing as an "ideal" consumer device, ever. MS are pragmatists above everything else. I'm staking whatever credibility I may have left there will NOT be a single cable tuner or card slots in durango, because it wouldn't make sense. This is just pipedreams, grasping at straws and wishful thinking. If it has any DVR functionality at all it's only relating to streaming internet video, which may not actually buffer/record to the on-board HDD at all, due to paranoid content providers worrying about their copyrights.
Content providers would rather all DVR stuff just went *poof* and disappeared in a puff of smoke, so that everyone would be slaves chained to their TV listings and commercial breaks.
