Besides windows mobile, What is the difference between smartphones and regular cellphones like my Motorola z9?
I don't even like windows so I'm looking for a reason why a smartphone, blackberry would be good for me. I use my cell for storing large amounts of music, and text a lot, and browsing the internet. So I'm seeing is it worth getting a smart phone and what is the point of it. Thanks.

Actually Windows Mobile is the difference practically.
A Smartphone is basically a PDA that includes mobile phone hardware and applications to communicate with.
Regular phones are phones first, and run a lower level OS
to perform their tasks.
