This was the day many people had been waiting and hoping years for… Google takes up the Open Source / Linux code base and enters into full competition with Microsoft in the operating system market. Now it is official, as Google announced on their blog yesterday. The “Chrome OS” will be, like Android, based on the Linux kernel and essentially a Google-sponsored re-write of the user interface over that to build a next-generation, cloud OS geared to run web apps. The most important point here is “browser” based vs. “desktop” based, because with that comes all of the potentialities of cloud applications, remote hosted drives, distributed computing, SaaS, etc. Since the Chrome OS is being specifically targeted at netbooks, many are also pointing to Adobe Air applications vs. traditional desktop apps as future standards. The last point though highlights the main asterisk to the announcement: the Chrome OS will be optimized for netbooks first, rather than desktop PCs, which most users and virtually all professionals & business users rely on.
