A great thorough read here on the Chromebooks market positioning.
Google: Going After Microsoft's Heart With Chromebooks
Google: Going After Microsoft's Heart With Chromebooks
Google just explained the business case for Chromebooks in a press briefing at I/O, and it's crystal clear that they're not a consumer product.
Rather, Google is going after Microsoft's heart -- the corporate IT department.
But what about Office? What about specialized corporate apps that only run on Windows?
Those are taken care of through a deal with virtualization company Citrix. Companies can set up a XenDesktop system, where all Windows (and other) apps are running on a server. Users can then access these apps through Citrix Receiver, which runs on ChromeOS (as well as other platforms).
Citrix demonstrated how easy it is -- users basically log on to a corporate "app store" and click the apps they need. They're automatically added to the Chrome OS startup menu.
