I have written about if before: updating programs on your computer - if you're not using a Linux distribution, that is - is a total and utter mess. On Windows and Mac OS X, there are roughly four ways of updating applications. The application notifies of new updates, and then downloads them when you click 'yes', the application updates from within the application itself, or the application requires a special update program running in the background. These are all quite annoying, since they interfere with your workflow (as opposed to, say, running "apt-get upgrade" every morning). The fourth method is the official vendor channel, Windows/Microsoft Update in Windows and Software Update in Mac OS X. Paul Ellis argues that to alleviate the mess, Microsoft should open up Microsoft Update for everyone else - and similar arguments are made concerning Apple's Software Update.
