Everyone wants what Microsoft's got, namely control of the most widely used computing platform. Or, more accurately, everyone wants the billions and billions of dollars that flow in from the dominance of desktop computing. Replacing Windows shouldn't be hard. Everyone hates Windows, right? That seems to be Google's thinking. The company announced this week that its shiny new Chromebooks will become available to order online starting June 15 in the U.S., U.K., France, Germany, the Netherlands, Italy and Spain. Chromebooks are laptops powered by Google's Chromium, which is an open-source, browser-based operating system. The laptops will be built by Samsung and Acer, and they will be priced at $499 if you want 3G capability, with Wi-Fi-only models available for $429. They will be available at Best Buy and via Amazon.com. You can also "rent" Chromebooks. Businesses will pay $28 per month and schools $20. Software updates are constant and automatic. Hardware replacement happens automatically with failures and new versions.Unlike Chrome, which is Google's browser application, Chromium has a built-in Flash player, a PDF viewer, an automatic self-updater and other features. Google claims that Chromebooks have multiple advantages over other computers, including USB storage, a limited file manager, offline use of apps and data, superfast boot times and 8.5 hours of battery life on a single charge. The company emphasizes that no data is lost when a machine is damaged, lost or stolen. Google co-founder Sergey Brin offered this analysis: "With Microsoft, and other operating system vendors, the complexity of managing your computer is really torturing users.It's torturing everyone in this room. It's a flawed model fundamentally." It shouldn't be too hard for Chromebooks to compete with "torture."It's true that Windows computing can be painful and is a flawed model. But there's one major problem with Brin's statement: His sales pitch exists in a theoretical fantasy world where there is no distinction between personal and business computing. When you think through the implications for these two markets separately, you can see that Chromebooks are best for neither.
