To some, computers are the biggest, if not the only means of productivity in their daily lives. These people need to feel comfortable with their computer desktops in order to be their most efficient. Knowing where everything is helps a person become familiar with their desktop’s organization and then helps them avoid doing more work than necessary when they want to use a particular program or window. OS X helps you to organize your desktop by providing a shortcut for switching between Applications. Apps are then broken down into Windows for each task. I prefer yet another degree of abstraction so I’ve installed VirtueDesktops (whose development has been discontinued, sadly) in order to allow myself multiple Desktops on which I can put many Applications. Each Desktop represents a category of tasks. “Browsing” is for Safari windows, “Mail & Chat” is for just that, Mail and iChat, “Other” is for iTunes and iCal and other peripheral tasks, and “Work” is for whatever happens to count as “productive” at the moment.
Enter the outsider. The one who neither knows how to make the most of their computer, nor cares that you are trying to make the most out of yours. She asks if she can use your computer to “check her mail.” She doesn’t know that your iChat windows are placed exactly where you want them to be. She doesn’t know that your setup was designed to prevent as many windows as possible from falling off the edges of your screen. She definitely doesn’t know that there’s such a thing as multiple desktops. When you get your computer back from her, you want to cry. Everything! As out of place as possible! I half expect my menu items to be rearranged!
These people offer the classic reason for having an OS that is aware of multiple users. These people must be allowed to log-in to their own sandbox environment. They ought to be able to have their own room so they won’t want to play with my toys! Just make sure your screen locks before they get to it. If they aren’t interested in learning how multiple Desktops work, then I shudder to think about how they’d react to explaining the necessity of them using a different User name!
