I'm very faithful when it comes to charging my iPod.
I do let it run down to maintain battery life, but never have I let it run so low as to forcibly shut down. When I did get a chance to charge it, iTunes wouldn't even recognize it for about ten minutes. When it finally did pop up into the iTunes panel, I let out an audible sigh of relief.
My cell phone? I'll let that sucker die a thousand deaths before I charge it. My iPod?
