Recommend a Tech Toys Bag?

SuperMallen asks: "With the recent purchase of an iPod and iPod-capable car radio, I am realizing that I have reached maximum capacity in terms of what can go in my pants pockets. Given that I want to take both the iPod and my radio face with me wherever I go (along with my cellphone, Bluetooth headset, wallet, keys, and possibly a laptop with mouse, power supply, and whatever reading material I'm carting around), I'm thinking that what I need is a medium sized bag or backpack with pockets dedicated for this sort thing. What does the Slashdot community do for things like this? Any brands or models you have found work for you?"
