When the iPod Shuffles were launched, I got a 512MB because I thought that I wouldn't really need that much space to store music.
I can always leave my CDs in the car, or use Yahoo Launchcast at work.
So I just loaded my favorite Tori songs, and a few others. Then, i started having trouble with Launcast and decided to bring my Shuffle to work.
I started to download and add more songs from iTunes and my CDs.
It will fit. That's what I thought, anyway.
I was wrong! I kept adding, and adding, and adding more songs. I wanted to load so many songs, I ended up getting a 4GB iPod Mini.
For now, it seems like it's just the perfect size. I've only used about a third of the alloted space. I'm soooooooo happy! I love my Mini.
