Looks like I'm a bit behind you guys in this category.
I don't have the luxury of drivespace, so Bleach, Higurashi, Shuffle, and Fate-Stay Night have been banished to the depths of DVD-R. Oh, and I've got Chrno Crusade and Azumanga Daioh on retail DVD. Besides those, my iPod houses my whole collection.
I only got into Anime about April of this year or so, but it looks like I'll have to invest in an external drive, since it's a growing and addictive habit. My favorites are Death Note, Haruhi, and Seto No Hanayome.
The first Full Metal Panic episodes are there just for the sake of completeness, haven't watched beyond episode 6 or so.
Jam it back in, in the dark.
