Wil Shipley, in a DrunkenBlog interview:

The two types of Windows users I've identified at my café are:

a. I use Windows to run Word and Excel and browse the web (and read e-mail in my web browser), and b. I'm a programmer and I spend all my time in a Windows IDE or hacking around with my system. I'm sure there may be a third category of user out there, but this has been my observation as well. My wife and parents clearly are the first type of users, and could just as well be served on a Mac. The SuperToad falls in to the second camp; he makes his living as a Windows programmer, but he does so with a Mac on his desk as well. Plus, he's still getting mileage out of a decrepit, original orange iBook. Since my switch to Macintosh over a decade ago, one of the reasons we have kept a PC or two in the house was due to my wife's work. She's a corporate attorney, and could always work from home, if need be. After our move to Dallas, the firm she worked for here had a VPN system set up, and she could work on items in the firm's document management system from home, just as if she was sitting in the office. Her new employer, however, being tied in to the stock market and the myriad regulations therein regarding insider trading, etc., does not have such a system in place. You work at the office, or you work on a company-provided laptop, or you don't work. Also, my wife's position also is not as intensive in outside-normal-business-hours work as her former firm life was. She doesn't need a PC at home any more. Last year, when her old desktop PC was giving up the ghost, and I set out to build her a new one, if we had known then she was going to change jobs, I wouldn't have bothered. I would have milked the old PC until after she moved in to her new career, then replaced it with a Mac Mini. Hindsight is always 20/20.
