I need a bag to carry papers/books to work.

I have a very dull black canvas one that I want to replace with something more stylish. My normal plan would be to buy in black, tan or navy blue because they are neutral, but I'm finding myself playing with the idea of something a little more fun...

I can't find Angie's post on work bags, (probably will once I've posted this) but does anyone have any comments on this - it's the green croc leather laptop bag on the second row:

I only have two handbags (!) - camel and bright pink, with the camel being the every day one at the moment. I want to buy a navy blue one as well. Am I crazy to look at this? I don't like the black version of the one I've linking to, but it's not an urgent purchase - I can wait!
