Does anyone have or seen a nice Matrix or Dashboard listing the capabilities between viewing a mobile website on a smart phone and on a non-smart phone?
I'm not sure this is a direct answer, but have you read this: http://www.passani.it/gap/

I'm not sure that all the capabilities can be summed up in a single chart. Programming the Mobile Web is an excellent resource for this though as the author dedicates multiple chapters of his book to that very question.

Your question is a little bit vague. What are you looking for specifically?
