OLPC Interface Video
A video of the UI for the OLPC project has been posted on YouTube.
It's definitely interesting and worth checking out. What do you think of it? It's very simple and should be easy to use, especially for people that have never used a computer before or very limited.
Personally, I like the UI. It is clean and very responsive for a computer like that.
I will definately buy the OLPC if it gets released to the public to amortize costs.
