Peripherals

This is a space for presenting XO peripheral ideas in a concise manner for review by the OLPC core team. Feel free to expand the description of your idea on a linked page but please keep to the formatting on this page.

Alternatively you may talk to me here, but do check my userpage for other ways to contact me.

We now have a mailing list: peripherals@lists.laptop.org

Also see Product News for product availability of some of the ideas discussed here.
