DS Daily: What do you look for in a case?

We've written about loads and loads of niftyways to store your games, but when it comes to cases, what really gets your blood pumping? Are you all about form or do you lean more toward function? Do you need something that can haul the maximum number of games, or do you typically take just one or two games with you when you're mobile? Do you tend to get a little creative? We'd love to hear about what you like, what you don't, and which cases are your favorites.
