What makes the OLPC XO-4 different from the XO-1.75 notebook is this – the former is a true, blue tablet, courtesy of the inclusion of a touchscreen display. Not only that, OLPC intends to make it far more sprightly by throwing in a dual-core 1.2GHz Marvell PXA2128 processor. This particular processor will deliver long battery life thanks to low power consumption, and yet it ain’t too shabby for average tasks that users in developing nations would use it for.
Apart from that, the wireless chip has also received an upgrade to 802.11n WiFi now. Similar to its predecessors, the OLPC XO-4 will be powered by Fedora Linux with the custom Sugar user interface, while placing a strong emphasis on educational software. Expect OLPC to mass produce the XO-4 sometime later this March, where they ought to retail for $200 thereabouts each with a minimum order of 10,000. Ouch!
