The title pretty much says it all. What do people think of Mozilla’s Boot to Gecko operating system? It seems similar in many ways to Google’s Chrome OS and Chromium OS, i.e., a Linux system stripped down to very little more than what is needed to run a browser, with all applications running within the browser. The main differences are that it uses a browser based on Mozilla’s Gecko rendering engine, instead of Google’s version of Webkit, and Mozilla is targeting it at smartphones, as opposed to Google targeting Chrome OS and Chromium OS at notebooks. It seems that the first smartphones using B2G will be sold in Brazil later this year or early next year.
