Google Vice President of product management, Sundar Pichai comments in announcing Chrome OS, that people want to get to their e-mail instantly, without wasting time waiting for their computers to boot and browsers to start up, really tends to point to an instant access to applications.

Though Operating systems that can get people browsing the Web in a few snaps is not a novelty, as other companies have had a head start on delivering on that promise - with Dell, Phoenix Technologies, and Xandros already delivering 'instant on' operating systems built on Linux. But the fact that Google being a household name on the net, is jumping into the market, might translate to more people likely to favour instant-on now.

'Instant on' by itself might not be a killer app, but beyond fast starts, Chrome OS also promises energy efficiency and an alternative to conventional 'thin client' computing.
