Title text: It's fun to watch browsers fumblingly recapitulate the history of window management. Someday we'll have xmonad as a Firefox extension.
This comic is a parody of the "Get a Mac" (also known as "I'm a Mac" or "Mac vs. PC") ad campaign for the Mac brand of computers. The ads personified the Mac and their competitors, the PC. The ads poked fun at the PC's terrible function while paying attention to the Mac's unique features. Each ad started with the duo introducing themselves as "I'm a Mac..." "... and I'm a PC."
The comic, however, presents them as identical to each other, since everything nowadays is done through browsers. (It could also be taken as a riff on xkcd's simplistic style, as they are literally identical.)
The title text refers to window management, which is software that controls windows on computers. xmonad is one such program, and Randall says that eventually it will be an extension usable with the browser Firefox.
Mac: I'm a Mac
PC: And I'm a PC.
Mac and PC: And since you do everything through a browser now, we're pretty indistinguishable.add a comment!
