Nokia n70,n80 and n72 . Which is better.

I have been using nokia 3110c to browse but it does not play videos that i see online. So i am thinking of buying one that can do so . Assuming that the above models can do so . Which of them is better in terms of applications,memory space ,down loading capacities and playing videos online. I have seen the belgium ones at emeka offor plaza ,main market onitsha btw the prices of ten to twelve thousand . So house which do you advice me to buy.
