I just noticed that the biggest app running in my work laptop, with respect to memory consumption is FireFox (3.0.4 if you have to know). It consumes on an average of about 500 MB worth of memory. Even Outlook, comes only a far second. Of-course i have Visual Studio, MSDN and SQL -server et-all installed. But FireFox beats everything hands down when it comes to the frequency which with i use them.
All other applications seem to support the browser, or launch it within themselves. No applications seems to be made these days, without web being their core interface and to that end again browser has become a a single point of access. Even VM’s seems to favour running their clients inside a browser window. When viewed from this angle, the rationale behind google’s shiny new web browser, chrome, becomes more apparent.
