Chrome OS — Google’s lightning quick operating system that’s based entirely on the Chrome browser — is due out the second half of this year (check out our report earlier this evening on its progress). We’ve seen some demos of it in action, and even tried out an early version ourselves, but there are still plenty of question marks as far as how people will actually use this thing. After all, while the browser will be able to accomplish most tasks, users are going to want some degree of multitasking, and there’s also the question of how users will be navigating Chrome OS’s basic file structure.
