OLPC (One Laptop Per Child) will have an interesting tablet at this year's CES, and is said to start off at $100. The tablet, named XO 3.0, is 8 inches with a resolution of 1024x768. The actual screen type will vary depending on how it is configured upon purchase; a PixelQi display will run you ~$100 over the original starting price and standard LCD screen.
Although, I highly recommend investing into PixelQi technology. Their displays don't just save battery life, they are extremely easy to read in sunlight - which has been an ongoing issue in standard LCD screens. However, you should be able to charge the XO 3.0 on the go with a hand crank or solar panel!
It may be tough to actually purchase one of OLPC's laptops because they will primarily sell them to countries in bulk. But I have a feeling there will be many more tablets with a $100.00 price tag during CES next week, so it will be interesting to see how they all compare. The XO 3.0 could come out the clear winner - but I'm not sure it's fair to compare OLPC to other manufacturers, as they claim to be doing this for the kids of the world - and not themselves.
