I am currently a SideKick 3 user and have been using the Danger devices since the Sidekick 2 came out a few years back. Compared to the iPhone, the Sidekick is a huge mass of phone, its' the web browser, camera features, and cell phone reception pale in comparison to the Apple device. There is one feature that the Sidekick has that really sets it apart in a good way from the iPhone, the keyboard. The SideKick has what I consider to be on of the best mobile phone keypads on the market. I am able to draft quite extensive emails and blog updates on the trusty little device with little effort.
