They may keep over 1000 songs on their ipods, but how many of those songs are they listening to every week? It is very easy to upload your top 100 once or twice a month, and keep the remainder on your computer.

As a side note, I use my mp3 player more for data transfer, and data backup than music. It is easier than using a disk.

Truthfully, I don't know how many of the thousands of songs they listen to on the iPod. And, since I don't own one, I can't speak from experience. However, I do know that an increasing number of people are using their iPods, laptops and desktops as the sole music systems now, which I find fascinating.

I may not listen to 1000 songs at any given time, but if I'm on the road and suddenly decide I want to hear "mas que nada", "hyperactive", or "Dr. Wu", they're just a couple of clicks away.

It's not volume, it's variety.

Some people also use them for audio books which usually take up several CDs.

It's also a good portable drive.
