Hello. I go to the computer lab on campus to do most of my work because I love the nice 20" dell lcds and I can get work done, rather than in my dorm room. I use my 4G 20gb ipod all the time, and always find it out of juice. I plug it into the computer to use as my portable 20Gb drive and also to charge it. If I cant find an outlet, and bringing a charger and firewire cable is a pain, can I charge it on the PC with USB and listen to it? Any hack to do this? Also, could I still use it as a disk while plugged in? Thanks (switching this summer when I can afford a MBP. Also, is there a way that the songs can be on the ipod like they appear on my PC so that I can just run the mp3s off the computer?
