You need to remember your not a business analyst telling Steve Jobs what the market wants from Apple.
As for streaming, no, it costs too much and BB speeds aren't there yet plus you have BB usage caps, this argument has been done before, I think it was before you joined this site actually.
People like to own there media and they don't offer HD content which yes you cannot play on a Mac, but you cannot link your laptop to an HD TV and get HD film's.
Also the last time I checked none of Apples software was offered as download, neither is Office for Mac, all the other apps people use, Windows, Windows games etc etc etc etc..... you can't make a family video and email it off to the granny unless your SP will let you send 5GB emails? And granny can download it..
And I refuse to argue with an idiot so they can bring me down to their level. Which is what you are because you are stating professionals
should not use a notebook for such purpose 


I can tell you haven't been on this forum very long......
