Welcome to the next installment of "Tech Talk." This monthly feature will hopefully help you understand about certain sound and musical gadgets that everyone sees but are just not sure how they operate in the real world.

This month we will be talking about iPods.

They have been around for a few years and millions have been sold . They hold lots of music, movies and photos. Let me try to tell you some differences between iPod Classics, iPod Nanos and the iPod Touch in case you have children (or anybody else) wanting these little marvels for Christmas!

iPod Classic

The Apple iPod classic is a modern icon, allowing you to pack an incredible amount of songs, photos, and videos into its slim, ultra-portable body. And now it's even better and more powerful! A built-in 120GB hard drive holds up to 30,000 songs in the great-sounding AAC format, while the iPod classic can also store up to 25,000 photos and hold up to 200 hours of video. Aside from being an amazing resource for listening to your favorite music, you can use the iPod classic to store and check your latest mixes!
