First Look At Final OLPC Design
There is one aspect of the OLPC that really worries me: the software.
There are alternatives - Pepper Computer's Linux environment runs on the OLPC. It's more mature than the OLPC software, and was designed from the beginning for consumers. It focuses on web browsing and media rather than education, although it's possible to run things like eToys too. Pepper integrates Firefox, MPlayer, Helix, and a number of other open-source projects into something much simpler and easier to use than your standard GNOME/KDE clone of the Windows desktop. If you're at CES, stop by the booth for a hands-on demo of Pepper on the OLPC.
