Laptop Carrying Gear?

jeffx asks: "Okay, it has been long enough and I finally bought a laptop. Not going to get into a great big discussion about what type of laptop I got but something that is just as important,.. the carrying case for it. I have so many gadgets my belt looks like I should be starring in the next Batman movie. So I don't want some silly business-looking laptop bag to carry my new 'gadget' in. I am fond of some of the backpack-looking cases but they still look too professional. So anyone have any input on what I should use to carry my laptop around in? I know this sounds like a trendy thing but before I got the 'right' case for my Palm Pilot I rarely used it. The case needs to be functional more than anything."
