Cargo pants are a nice thing if you're in a situation where they work. I wear them when I'm shooting sports and they're great for that. I generally avoid them for normal wear, though, except ones with really subtle cargo pockets.
Kuhl's pants are pretty cool (no pun intended), and they make some awesome cargos. I have a non-cargo pair, and would've bought some cargos except that they didn't have my size at the time. The pocket design on them is really cool, though.
