Like at least half the nerds in America, I applied to be part of Chrome OS beta testing program as soon as it was announced last week. On the surface, at least, I figured myself to be an ideal Chrome user?to a sometimes-scary extent, my life is already lived in Google?s cloud. Even on a Mac I default to the Chrome browser, where I write in Google Docs, check my feeds in Google Reader, and even sync Google Calendar and Contacts to my iPhone and iPad instead of paying for MobileMe. The company?s cloud-based operating system seemed the next logical step.
