Accessorizing the iPod is big business and the consumer electronics industry has responded in a big way, producing a wide range of iPod-compatible accessories. CE Pro has just published an article about iPod-integration design considerations. Some of their key points involve providing an accessible product that can be used away from computers and in real living situations like the living room and the kitchen and allowing users to fully access the iPod's libraries. It's an interesting take from a designer's rather than an end-user's point of view, and worth reading if it's the sort of topic that appeals to you.
