英语时差：iPod常见问题

Thanks to Apple's effective marketing campaigns, the term iPod has almost become generic for "mp3 player." But buying an iPod is not so easy, and first-time iPod customers have many questions.

Q: What's the difference between the various iPods on the market now?

A: The larger iPods are generally the most expensive, but offer higher capacities, video playback, photo storage and other interface niceties. The Nano and Minis are significantly smaller flash-based devices that are fashion accessories as much as they are playback devices, as they come in a range of different colors. Which one you decide on will hinge on personal preference for size, capability and handling.

Q: I've heard that I have to use iTunes if I purchase an iPod. Is that true?

A: Many people have the wrong impression of iTunes. While you can purchase music through iTunes, you can also use it to organize and transfer to your iPod songs that you already have on your computer. The iTunes application performs many of the same functions as the Windows Media Player.

Q: How long do the batteries on an iPod last between charges?

A: Depending upon the model you buy, battery life is between 8 and 14 hours. Your iPod charges when it's hooked up to your computer. You can also buy a conventional power adapter from Apple or third parties.
