DAPReview checked out the Creative Zen digital audio player which features 20GB storage capacity, here's a snip from their review:

My first DAP was a 4th generation iPod. It was a great introduction to digital audio layers, and as a music device it was more or less flawless in my opinion (equaliser issues being the only major down side). Eight months later, I decided to try something new, which turned out to be the new Creative Zen (period). It featured a user-adjustable 5-band equaliser and FM Radio (with recording) and a Microphone, and it seemed like the perfect upgrade rom an iPod. Its had a greater featureset, but most of all, it seemed as if the Creative firmware was finally maturing.
