I'm not exactly sure about that yet. For now, the focus is to ship _something_ that works. Since I'm not exactly sure how migrating to a bigger sd card could work in a user friendly way (apart from getting a card reader and cloning it, which is not feasible for everyone), I have considered implemening a USB storage option, which may still need a USB hub and an external storage, but is much more versatile than using SD cards. It might be faster as well.

As for the case: I'm talking with the great guys at ModMyPi to produce cases for me. As soon as they confirmed that I'm good to go, I'll update the page.
