Serious video editing requires a lot more than 100GB, so I use an external drive for all my editing (300GB in a FW/USB combo enclosure).
Music takes up space, but I only have 4-6GB of music
Photos take up space, but my 13000+ photo library only takes up 12GB.
Admittedly, I'm picky as to which apps I have installed, but my Applications folder only has 10GB used.
I consider myself a serious computer nerd, but I don't see how 100GB really is that much more helpful than 80GB. For $100, you can get a 160GB external drive (or even a 60GB pocket drive).
