Thanks Glynor - yes, it was presumptive, and yes, I purposely said so - trying to see how the mainstream and minority users view the various interfaces.
What started the train of thought was playing around with Front Row and Apple’s 6 button remote [Up, Down, Left, Right, Play & Menu]. Without comparison to the actual product, iTunes is for the keyboard & mouse whilst Front Row is purely for the remote.
With reference to Jim’s list, I would suggest (better Glynor?) that Touch screen & Mouse are nearly the same. I would also guess that if you have a mouse, you’re likely to have a keyboard. And lastly that if you can navigate by mouse, you should be able to navigate by arrow keys. I suppose the more specific question should have been; What is the Primary interface method for each type of view?
Theatre View Remote & Touch Screen
Everything else Keyboard & Mouse
