I've got a women's Nomad and like it - I don't think there's any different between the men and women's (hubby has a men's one) except color options. And while I'm not a fan of pink, plaid is pretty cool. :-)
Dakine's got some pretty funky fabrics and newer packs have some slightly different features from older versions (pocket for mp3 player, side zip pockets that are easy to reach for cell phone and tools without taking the pack off). Both newer and older versions have a pocket lined with soft fabric for sunglasses, and in the fabric bit on the outside there's a hidden water proof pocket.
I've used Deuter and Camelback packs before too, and the features and fit of the Dakine are definitely my favourite.
If you're looking for one that's a little more unique:
(and yes, they are easy to wash, just empty and throw in the washing machine)
