As a reply to my ARM Powered Chromebook Chrome OS notebook question posted online, the Google Chrome Team confirms that while they are focusing right now on getting the Intel Powered Samsung and Acer devices out the door on June 15th, the Chrome OS team is also working hard on ARM support and the ARM Powered Chromebooks should be released soon after. Their wording is the ARM Chromebooks are "hot on the trails" of the Intel Powered ones. This could be the first mass market ARM Powered laptop ever released.
The advantage of an ARM Powered Chrome OS device is that it is thinner, lighter, runs longer on a battery and especialy could be sold for a lot cheaper. I'm expecting the ARM Powered Chromebooks to sell below $199 for them to become the new best selling notebook platform.
