Smartphone interface is very often the cover by which we begin to judge the book. The layout, designs, and color scheme play a heavy role in how easy it is to navigate and customize the phone' but we also can't underestimate the UI's emotional connection.

So let's not. Instead, let's have an interface-off that lines up ten smartphone interfaces for scrutiny. Six platforms are represented--iPhone, Windows Phone 7, BlackBerry OS 6, WebOS, Android, and Symbian 3 (we rate four different Android "skins,") and we'll spill our guts on exactly what we think of each one.

Feel free to join in the fray to applaud, denounce, or defend your smartphone's interface. '
