The bottom of the iPod Nano includes a Apple universal dock connection and a headphone jack.

The iPod Nano measures just 0.24 inch (6.2 millimeter) thick, and weighs 1.28 ounces.

The fifth-generation iPod Nano marks the first time an FM radio has been included in an iPod.

The screen of the fifth-generation Nano measures 2.2 inches diagonally, up from the 2-inch display on the previous model.

Apple added a new pedometer feature into a "Fitness" submenu that lives in the Nano's "Extras" directory along with games, voice memos, alarms, notes, and so on. It's cute and it works a little like a poor man's Nike+iPod kit. In fact, iTunes will even prompt you after it sees you've used the pedometer, to see if you'd like to track your progress on the Nike+ Web site.

The Nano's camera is located on the back of the device near the bottom, making it problematic to hold without blocking the lens.

The iPod Nano is one of the slimmest, lightest, and most portable MP3 players on the market.

The fifth-generation Nano now includes a built-in speaker, making it easier to share audio with friends.

The Nano records 640x480-pixel resolution standard definition video at 30 frames per second. Files are recorded as iTunes-friendly MP4 videos with h.264 formatted video and AAC audio. Video quality looks, well, decent.

In a head-to-head video recording comparison test between the $199 Flip UltraHD (shown left) and the $149 Apple iPod Nano (shown right) image quality differences were immediately apparent.
