This question is directed to those of you who own a video ipod and have used one of the recording accessories for it such as the one from xtrememac. I am a college student and I record my lectures with a crappy sony recorder. I want to get a nano and an accesory (hopefully they come out with one soon) that can record my lectures. My question is how big are these files when you record them? I have a very small music collection but I've heard that recording takes a ton of space. So i'm wondering wheather to get a 2gb, 4gb, or 8gb. Thanks.
