I actually rely on my CD/MP3 player, since sometimes I need to play a Audio CD when asked, and I couldn't do that on a portable MP3 player. My CD/MP3 player doesn't have a backlit LCD... and sometimes that's a problem.
Now... to help DNJ... if I was in the quest for a portable mp3 player, my choice would be the creative jukebox.
Why? Because of the line in input! Of course the IPOD is smaller and lighter but with the Jukebox You can record a performance directly to WAV format (that is: without any kind of compression), and burn a Audio CD later! That's great! That's like having a MP3 player and a excellent recorder (like you were recording to the computer)! A lot better than a Minidisc recorder, where compression is used.
