At first the developer version of Chrome OS with the Aura desktop manager looks pretty much like the old Chrome OS except for the dock at the bottom.
Read my blog for more information about the new Chrome OS.
But, what’s this? Chrome OS now gives you a background and lets you launch applications from the dock just like Mac OS X.
You can also now have multiple windows on the Chrome OS Aura display like so many other older operating systems.
You can also quickly get to all your installed Chrome OS applications on the main Aura display instead of within a Chrome browser window.
Finally, the new Chrome OS makes it easier to get to the operating system’s nuts and bolts such as its task manager.
