You guys are totally mistaking.
You are thinking like tech-savvy people. Since most of us here are webmasters, this OS is "totally" useless to us.
Google is NOT aiming the OS to us, Google is targetting a SPECIFIC group for this.
This is the group of the "stupid" consumer. Who goes to Best Buy, and asks if the "Toshiba Satellite" is better because it works off "Satellites," rather then this "HP "Pavilion"...
Almost all consumers only use PC's for internet, and since google is making new apps in the cloud for other things (docs, pictures, videos). Thats all they need.
This OS is not a full OS in the sense of how we use it, or how business or power users use it.
But for the non-tech people, this will sell. Also they are driver specific, so they will be laptop specific. They know what their doing. In a year or two this totally sell. Look for google to create maybe a full Linux distro 2 years after this one hits the market, one that doesn't use "The Cloud" as its main productivity.
