I’m a little late on this but the OLPC project seems to be on full swing now.  Between November 12th to November 26th, you can make a donation for a child in a developing country and in return get one for yourself.  The donation is $399 and $200 of it is tax deductible.  Additionally, you’ll get T-Mobile’s HotSpot access for a full year for free.  Check out the details here for the Give One, Get One promo.
