I've just tried to point out several times that as our iTunes Libraries have grown larger than the largest capacity iPod available, it would benefit the "I need my whole Library with me" crowd to learn how to use smart playlists to bring along a good representative mix and maybe even save you some $$$ from buying the next biggest capacity. I stopped at the 60GB when I recognized my listening pattern was better suited to a smart-rotating playlist than always trying to have the capacity to sync everything.
I like having my whole library.
Sometimes I one song will pop into my head, and I'll be like dammit I wish I could listen to that.. then I realize that of course I can, it's all on my iPod.
Granted I only have 5.00 GB of music
Hell I wouldn't mind having whole seasons of TV shows on my iPod, and I've enough space to do it... couldn't really do that with only 16-32 GB.
