This year at CES, I saw new Chromebooks from Samsung, and Google has announced that they're on the way to consumers, along with Chromeboxes. You can even try them out at some Best Buy stores. The new Chromebooks are faster, and the Chrome OS has been updated to be a little less jarring for the average new user.
Don't expect it to be a runaway hit anytime soon. There are still a few things missing from the models I saw. Backlit keyboards, bigger sizes, more apps, and child accounts.
Child accounts may not be something everyone needs, but it's something I can get out of my Mac, PC, and gaming console. Currently you can only log children into Chrome OS by using your account (in which case they could buy apps from the Play store with your account) by making a separate children's account (in which case you violate Google's terms of service if your child is under 13) or by logging in as a guest (in which case you can't track your child's Web history.) There needs to be a better solution.
