As with all iPods, the second-generation model supports playback for MP3, AAC (including protected files), Audible, WAV, AIFF and Apple Lossless. There's still no support for WMA music files, but you can always convert your WMA tracks to MP3 within Apple's iTunes software.
If you're looking for a way to take video on-the-go, the touch has plenty to offer. You can load it with video podcasts, TV programmes and iTunes movie rentals, or watch endless amounts of free video clips using the included YouTube widget. Viewing angles seem better than the previous model, while colour balance and brightness seem about the same.
Apple rates the new iPod touch at 36 hours for music (up from the first-gen's 22 hours) and 6 hours of video (unchanged), although mileage will vary based on screen brightness and Wi-Fi usage. Historically, Apple's iPod battery estimates tend to be conservative.
We think the second-generation iPod touch is one of the best iPods ever made. Inside and out, it's in a league of its own in the world of portable entertainment. If you have an old, worn-out iPod and you're ready to upgrade, we think this new model should be your first consideration.
That said, if you already own an iPhone or an original iPod touch, it would be hard to justify buying the second-generation version. Also, if all you really want is a no-frills portable music player, upgrading is probably overkill.
