OLPC XO-4 surfaces at the FCC, right on cue


The One Laptop Per Child team hasn't always been punctual -- see the XO 3.0, née XO-3 -- but it should be right on time with the XO-4. In step with March production plans, the ARM-based portable has passed through the FCC's approval in both conventional and touchscreen flavors. All models share 5GHz-capable 802.11n WiFi as well as Bluetooth; there's no cellular surprise lurking underneath, if you're curious. More than anything, the filing is good news for students in the developing world, who are that much closer to touchscreen laptops at a time when the technology is still fresh for just about everyone.
