Chrome is designed to be a very significant browser. Couple it with Google apps and stuff built to an API called Gears and you have a portable mini development platform. Windows, Mac, Linux, whetever. Verrry interrresting. From Google's business point of view it is a TV network in which internet browsing and apps are the programs and Google sells advertising. Brilliant. From our point of view new competition in the computing arena. Good.
The marketing approach starts with a comic book aimed at techy types explaining the design aims, approach and key choices. It will be very effective at getting good buzz going.
