This is a non-sequitor. The fact you have given, "When you close the top, the comuter will go to sleep", in no way justifies your conclusion,"

1) I can charge my ipod using my ibook, even when the ibook is sleeping. I do it often. I note that when I do this, the battery icon (top right of screen) is animated. I have observed that the battery is indeed recharged after being plugged into a sleeping ibook.
2) I recommend not charging your ipod off of your computer when it is not sleeping. My rationale is that all mechanical systems fail, why accelerate the process by excess wear? If you think the excess wear is negligible, consider the following. When playing your ipod, how much does the hard drive spin? In my experience, if I am playing songs continuously and not jumping from song to song, the hard drive spins for five seconds every 5 songs (or about every 15-20 mins). So in an hour, the hard drive spins about 15 seconds. Now consider if you plug your ipod into your computer (while it is not sleeping) for one hour. Your ipod's hard drive would spin for one hour. One hour of hard drive spinning while charging is approximately 240 hours of hard drive useage for an ipod being played continuously. Now, for most hard drives, you can find data on MTTF (Mean Time To Failure). This is a measure of the expected life of the part as measured by useage.
3) Somebody mentioned the warranty of your iPod. Have you checked how long (or I should say, how short) your ipod warranty is? Look it up, you may be surprised.
In conclusion, charging an ipod from your computer while it is not sleeping provides increased risk, with no advantage. It just isn't worth the risk.
