The One Laptop Per Child (OLPC) “Give One Get One” program is now open in the United States and Canada until November 26. During this time, you can donate the revolutionary XO laptop to a child in a developing nation, and also receive one for the child in your life in recognition of your contribution. The cost? $399 — $200 of which is tax-deductible. Another bonus: For all U.S. donors who participate in the Give One Get One program, T-Mobile is offering one year of complimentary HotSpot access.
