Dell DJ vs. Apple iPod
Concrete and Not-so Concrete Reasons:
1. Lighter, smaller.
2. Much better UI, I've had the unfortunate experience of actually using the Dell DJ and the iPod's scroll wheel is much better.
3. Extras: the iPod has games, contact information, an alarm, a clock, playlists on the fly, it can be used as a firewire drive for backup or for moving large files around.
4. It works with the best digital music store out there, as well as Mp3, which you surely have a thousand of. Not that Dell can't, but the iPod doesn't just play AAC.
5. I know I've already said it, but iTunes/iTMS, I know there are the others, but this one is still overall the best, the others have a few neat items, but they require too many sacrifices such as renting your music and using the always lossy WMP to be worth it. Also, iTMS has books on tape!
5. It has a heap of after-market parts including the dock, a hundred different case designs, FM transmitters, card readers, extra batteries, car chargers, etc. More are coming.
6. It is on its 3rd generation, at this point the bugs have been ironed out, even the battery issue means it can be replaced by Apple. And that's the downside.
7. Dell rushed this thing, it's certainly full of interesting ways to loose you music or die at an inopportune time. Plus, Dell IMHO can barely ship a desktop without replacing the motherboard twice, what makes him think this is going to be any better.
7. a. It looks cool, has a good mindshare, musicians such as Felix Da Housecat love them.
b. iPod jacking, it sounds weird but people do it, no one is going to give a rat's ass about the Dell.
8. Stop encouraging companies to simply wait until someone builds on a cool idea and then copying it into oblivion.
