Not many people have seen or used the Sugar interface supplied on the so-called $100 laptop (or One Laptop Per Child) project, but Harry Brignull has posted a video that provides a quick tour. His post is entitled Why the OLPC needs lots of usability work, so you'll understand he's not wild about it.
The justifications for Sugar are available in OLPC Human Interface Guidelines. You can read those later!
There's also a video interview with Nicholas Negroponte on the $100 laptop.
Note: watch the video at ivr-usability.com, not the YouTube version. As usual, the YouTube quality is crap, and in this case, it makes a dramatic difference both to the legibility and the overall impression.
