Computers need operating systems. Even computers that do nothing but run Web browsers need one. An Application like a Web browser–Internet Explorer, Firefox, Google Chrome–needs to run on top of a platform that gives it access to the hardware resources of the computer (the memory, the persistent storage, access to the networking and communications hardware, the screen, the keyboard, and so on); to peripherals plugged into a computer (printers, cameras that connect, memory cards); to the other software on the the computer (like the system for storing files); and lastly, to you, the user.
Or do they? What if you combined the operating system’s functions with a browser’s functions, which include accessing and displaying Web pages, keeping track of bookmarks and passwords, and connecting to computer-attached resources like Webcams?
Google is answering that question with Chrome OS. Google is saying, with this product, that the modern computer user spends so much time working with Web-based resources that the main control system for the computer should be the browser, not the operating system. Furthermore, Google sources tell us that the Chrome OS experience will bear little resemblance to existing way that users interact with their computer’s main control program. A person familiar with the Chrome OS project told us, “All existing operating systems predate the Web, and the user interfaces are stuck in a desktop metaphor.” The Chrome OS, we’re led to believe, will be very different.
How? We don’t know. It’s a safe bet that the Chrome OS will lean more heavily on so-called “cloud storage” products–like Google’s own productivity suites, Google Docs–that let users store their data and documents not on their computers but rather on the systems of the Web apps they are running. The great thing about cloud storage is that it’s untethered to any individual user’s computer. Log in to your Google Docs account from anywhere, and there’s your whole workspace, right in front of you. It’s liberating.
Google may also take a cue from its own e-mail application, GMail, which blends the traditional idea of having folders for e-mail with the concept of “labels.” In GMail, you can drag messages into folders to file them, or you can drag folders (or labels) over messages to categorize them. It’s the same thing, but the hierarchy people are used to in operating systems, where a file is in one folder at a time, and the folder may be nested in another folder, is simply not there. Folders and labels are interchangable and far more fluid.
But in Windows 7, Microsoft’s next operating system, Folders are also less rigid than they’ve been in previous versions of Windows.
We can also expect that the Chrome OS will borrow user interface elements from Chrome the browser–like a tabbed metaphor for switching between “apps,” and the mind-reading command line (address bar in the browser). It may also evidence Google’s traditional obsession with clean (if not necessarily attractive) design and speed. The Chrome OS should be fast.
