Cellular access is one thing, but smart phones now carry the burden of having to have multiple forms of connectivity. Both the T-Mobile G1 and Apple iPhone offer access to Wi-Fi, while the Storm does not. All three also have some form of GPS capabilities, though the T-Mobile G1 takes it one step further offering traffic, satellite and street-level views from anywhere.
The lack of Wi-Fi knocks the Storm out of the running, and while the iPhone and G1 are pretty much on par, the nod in this category goes to the G1 for its innovative use of GPS along with its Wi-Fi integration to supplement 3G connectivity.
