I have an iPod and love it! I just flew to Europe, 8 hours, single charge. I also love how damn fast and easy it is to load all the music. I have a USB Rio and OMG! I am actually glad it has only 64MB!
The other plus is its size and weight and so easy to select from your 1000 songs. I have 687 songs and the drive is 1/2 full. If you have a Mac, I know most of you don't, but if you do, it also serves as a firewire drive whci is cool. I put some stuff on to have with me if ever needed. All and all I am very happy and bought a second one for my wife when she works out. Good luck with what ever you buy!
