One Laptop Per Child is planning to end the production of its XO-1 laptop as well as drop AMD’s x86 Geode processor. OLPC intends to replace these with a low-powered ARM alternative in the XO-2 laptop, which is slated for release in about 18 months. Even though the current XO-1 model consumes a mere five watts, OLPC feels thats the biggest problem. “We’re seeing some very impressive system-on-chip designs that provide both fundamentally low-power demands and the kind of fine-grained power management … in the XO-1,” said Ed McNierney, chief technology officer at OLPC. Though using ARM architecture will reduce power consumption, it puts using the full-fledged Windows OS on their laptops in jeopardy. The company is currently wrestling Microsoft in order to try to get them to develop a full version of Windows to be able to run on ARM processors. It’s not likely Microsoft will budge on the subject as ingrained as x86 is and how seemingly little there is in it for them, but we’ve been surprised before.
