I have a "normal" IPOD 40GB, and I love it.
I connected it also to my home stereo(marantz) system. There it also gets power. The battery live is not very long(I heard). But I use it only without power when I go out for a 3 hour walk, and 3 hours is of course np.
In car+home it gets power, so great for me. But from what I understood the battery life if not very good. Sound quality good, and not buggy for me.
I download my MP3's from
www.allofmp3.com since Itunes was not available here when got it.
