Ok, the iRiver is also quite the ripoff (at least the H120, the only one that truly competes with the iPod). There are only three features that are appealing, and they have balancing points.
First, they claim to offer up to 600 hours of music, but there's a catch.
That's only if you use OGG files for all your music. Now, I have over 5 GB's of AAC and MP3 files, and I'd rather not have to convert them. Of course I could keep the MP3's, but the AAC files will not play, and they make up over 90% of my library. Also, that would put me back on par, or actually behind the iPod in storage capacity, considering it's still only a 20GB drive, instead of the iPod's max 40. Even the closest in price is the same size for $30 cheaper.
Built in recording seems nice, although I'd be interested in what type of quality it gets. I'd kinda prefer an iTalk, as it would still bring to total price to around the same amount, and I believe is better quality, plus you get a small speaker on the iTalk. Balance that with the disadvantage of USB 2.0 instead of FireWire, and the iPod is still on top.
Last, there is the battery life. I get 8 hours or more on the iPod, but it does occasionally die on me after work on the way home, which I do not particularly care for. However, the interface clunkiness would cancel that out for me, and I'd rather have an easy to use player than one that plays longer, because I won't be playing it very much at all if it's not easy to use.
In addition, the iRiver is nearly a third thicker, taking up extra pocket space (already at a premium). I'm sorry, but my iPod is just the right size, and adding that much dimension to it is just not going to cut it.
