How else would you get your songs on to the DJ or the iPod? You have to have them on the computer to transfer them. Either way you can erase them later, but as others have said why would you? Having files on a drive doesn't slow it down. That may have been the case years ago when drives were in the MBs, but even that may be an urban myth. Plus, the transfer process is much easier on the iPod vs. the DJ. I've used iPods, very easy. Never used a DJ personally (don't know anyone who has one... anyone), but every review says the same thing. That it's a pain in the butt to do anything with it. Transfering MP3s or AACs are very fast and simple with iTunes, as are transfering files by using it as an external USB or FW hard drive.
How old is your daughter? It just shocks me that anyone would rather have a DJ over an iPod. There's a reason people pay more for the iPod, bringing it to 82% marketshare, while Dell has to lower prices on the DJ to break even point and they still don't sell.
Edit: I see from a previous post she is in High School. And taking AP classes to boot. There is no way she would enjoy the DJ more, she should know better. Perhaps she just doesn't want it to get stolen.
Even if she has WMA files, unprotected of course, you can change them to MP3 or AAC in iTunes for Windows. If she had protected ones, you can burn them to a CD and re-import, or (as a
last resort) buy some kind of iRiver or Rio or something. The iPod is the coolest and easiest to use MP3 players out there, especially the mini. You can even buy a microphone for dictation and a bunch of other accessories for the regular sized models.
It just baffles me that anyone would
WANT the DJ, especially over the iPod. Even if you hated Macs. It is
THE MP3 player. Ask her why she would want one and please let us know, because I just cannot wrap this around my brain.
And I took AP classes too.
