MS is wanting to replace DVRs. Do most DVRs stream to phones and tablets? I think DISH has a service such as that, but none of the Comcast boxes I've received had this capability.
The PS3 can stream to a phone, other tv, or tablet? I did not know that.
Sure, they all have application marketplaces nowadays, but the new xbox marketplace will have a platform that is shared with W8. Plus, developing a 3rd party app for the Roku(a garbage SDK) will be much different than developing a 3rd party app for the new xbox.
I live here in the UK. I doubt people would want to replace their Sky+ or Virgin+ boxes. Perhaps they have no need for regular freeview, but that wouldnt be a selling point.
Perhaps not PS3, but Sony have already made plans for Mobile devices, tablets and etc to stream content from PS4 already. PSP already does that with PS3, expect Sony to expand this by allowing iOS and Android deviced to stream content from PS4. Also streaming content from PS4 isn't a big deal, things like Netflix and etc are on smartphones and tablets anyway.
Again I meant all these apps will be available on everything anyway, well the most popular ones that people care abot. For example Netflix app will be avalable on Apple TV, Roku, PS3, PS4, Smart TV and etc. As for Windows 8 ecosystem, I don't think people give a shit, its not as if people care for Windows 8 now.If a app like Netflix was exclusive to Windows 8, then it would be a big deal.
Again, all this media features are nothing new, I expect both Durango and PS4 to implement IPTV and services as it is a natural evolution to have these things, but it isnt a big deal and its nothing new.
