Google announced today that the new ChromeBooks, are available to pre-order from Amazon and Bestbuy.The Acer and Samsung models are basically the same but they do differ in some aspects, as you can see from the specifications below.
Chromebooks are designed to increase productivity by eliminating the long and what we take for granted, the boot time and application availability. Once you open the lid of a Chromebook, it will be ready in just 8 seconds and connected to the world via, either 3G or WiFi. The Chromium OS will be updated automatically and as needed without needing user intervention.
Pricing range form $380 to $500 depending on the features, mainly 3G or WiFi.
I am still playing with the original Chromebook and have been quite happy with it.
