I recommend some real MP3-Players.
How about Jetaudios iAudio G3, the iAudio U2 or the quite rare yet amazing XDRUM 403?
The weak battery life and the dependency on a LiIo battery and the recharging time of ANY iPods make them poor choices for any real MP3-Player Addict.
I just gave you some ideas. I personally value the iAudio G3 highly, the XDRUM has only USB 1.1, as a multifunctional USB-Stick / Radio / MP3 / Voice / with inbuilt 70mW Speaker with LED-light and retractable USB-connector (no need for a cable) it would fit my demands exactly, but unfortunately it has only USB 1.1...
The iAudio G3 not only features great sound (I have heard it, and almost immediately wanted to buy it, but I resisted ...) but also amazing 50 hours of battery life. Even if you cut this by a 25% margin, trust no claim by the manufacturer, it is great.
Sorry, iPod-Users. Your white brick is even too expensive to use it as a coaster for whatever reasons, or to throw it at people. But you can sell it on eBay and look for a reasonable MP3-Player there.
Just take in mind, minimum output power should be 2x 10 mW... the more the better. Battery Life should exceed 12 hours. Flash players are more practical than HD-players, 1 GB is no longer unreasonable to ask for. USB 2.0 is a huge plus.
But... the mini Ipod is still a nice toy for the MP3-Beginner. After the initial clamor, you can nail it to the wall, but I still suggest selling and getting a reasonable MP3-Player.
Stop the iPods. Get better quality and more features for a lesser price!
