iPhone vs. Treo

I know we have MANY Treo users in our Mod-Blog readership, so they may be interested in this discussion with two Treo addicts of how the iPhone stacks up against the Treo in pretty much every category. The most interesting observation so far to me is that the lack of removable battery is what held back the original Treos from taking off, and may similarly cripple the first generation of iPhones.
