One Laptop Per Child (OLPC) is unveiling two new low-cost tablets today that are designed around young childrens education. Named the XO-2 and the XO-10, the tablets include 7-inch and 10-inch displays, respectively, along with Bluetooth, GPS, and a quad-core processor, making them some of the most capable hardware with OLPCs name on them. Both tablets have been customized with OLPCs educational software and distinctive green casing, but their hardware is actually produced by Vivitar. Their educational software appears bright and welcoming, and theyre filled with apps developed specifically to help kids learn about math, science, and other subjects through the guise of teaching them about their dream career.
