If the rumors are true than Google is going to launch its first netbook based on the Google Chrome OS with marketplace. Rumors say that Google is going to launch a table on black Friday based on chromium. Most probably on the December 7th, Tuesday Google may announce about this officially.
It is believed that HTC has made around 65,000 atom processor powered netbooks for the Google employees and it will be tested by them before the mass launch. Most probably chrome is going to be a cloud based OS that needs least resources at client-side. Chrome 8 is going to be the first version that supports the Chrome web store.
If the applications are transfered to the web than performance and cost issues about the netbooks can be solved very easily on the long run with a cloud based Operating system. This kind of device needs less processing power and storage space and can transfer most of the work load to the cloud on the web.
