In fact, its quite rare to find me without my PowerBook. But what I do for living is support Wintel machines and users. I support applications, network issues. And I have determined that I will never spend my own money for a wintel box. You see, in my philosophy, the computer should not be the point.
Computers are tools, nothing more.
A tool for work productivity. A tool for communication. A tool for entertainment. Most people do NOT want to fiddle with or fix their computers. At work, people want to write that memo or report.
