Actually, one thing was brought up that I hadn't considered as a unique feature before, and that's audiobooks. Can other players play Audible's format like the iPod can? Also, do other players pick up where you last left off in the audiobook like the iPod -- and iTunes -- does?
This is such a small feature, but it really is quite nice. I don't know if any of you have had to fast-forward through an audiobook to find your last stopping place. That is a big hassle that you eliminate with the iPod and iTunes.
Also, it's worth mentioning that because the iPod is the most popular option, there's some nifty options for accessories that aren't available -- or aren't available in the same variety/quality/whatever -- for other players.
The Altec Lansing InMotion speakers come to mind.
I think what it comes down to the most, like others have mentioned, is if you're a geek who likes to tinker, you might be bothered by the limitations of the iPod and iTunes. If your first requirement is to organize and listen to your music anywhere you go, and you like sleek solutions but maybe less ability to mess with the stuff under the hood, the iPod should satisfy you.
Here's a good litmus test...
Ogg Vorbis.
1. I need to go to the mall. Where are my Manolos?
2. Is that a character from Star Wars or something?
3. Makes my eyes glaze over. Do you want to play DDR?
4. That's what the hardcore kids are doing these days.
5. Ugh. That's so 6 months ago. I've encoded all my music in <some other, more obscure format> now. Get with the program, you valley girl.
If you scored 1-3, an iPod is for you. If you scored 4, you will find an iPod to be like nails on a chalkboard. 5+: You glare at anyone you see with white earphones, further ensuring your dateless status and participation in the next several years' worth of LAN parties in your metropolitain area.
