OLPC is available for the US and Canada public starting today. For $399, the customer will receive two OLPC, one for the customer and one for a child in the developing country. Customer will also receive one year of free Wi-Fi access.
The OLPC availability is limited, the sale will start on 12th of November and ends on 26th of November. I know you can get Asus Eee for the same price; however buying OLPC also helps a child in developing countries.
