Oooo bags. I need a new bag, something that I can carry on the train or on my bicycle rack. Here's one front runner:
It's a hybrid messenger/pannier bag, clips onto a bike rack but has shoulder straps. Water repellant for all our rain and comes with a waterproof cover for those heavy downpour days. I had to wear my messenger bag under my cycling rain jacket Thursday so I'd rather have a good bag I can wear outside for the 200 days of rain we get a year. It's nothing as nice as what PJungnitsch posted but for its versatile utility I think it looks pretty good.
I'm not a backpack person. They don't look good with work clothes and they're hot to carry while cycling in the summer.
