Here is the Palm Pre's main home screen. In the upper-right corner, you'll see your signal strength and battery life. Along the bottom are the quick launch and notification bars. The quick launch tray includes shortcuts to the onscreen dialer, contacts, e-mail, calendar, and the main menu (aka Launcher).
By the way, if you want to take your own screenshots, just press the orange, Symbol, and P buttons on the Pre's keyboard. You'll then find the screen captures in their own folder in the photo roll.
