Most graphics people I know give a good reason for their request for Macs in the workplace. "I work better on it, it has good color reproduction, and having one at the office will make it easier for me to work from home." Believe it or not, graphic artists aren't actually stupid. They know what tools work best for them, and they tend to like the Mac's workflow, especially in Adobe applications, which attempt to emulate the Mac's document handling on Windows (poorly).
Believe it or not, I agree with you on this point. I also wish that Adobe would, instead of attempting to emulate the OS X UI model on Windows, design the UIs on their Windows products to instead adhere to the normal conventions of Windows software. For this reason, on Windows, I prefer *using* Corel, but unfortunately Corel is somewhat dangerous to use in a print production workflow due to occasional unexpected ahh misinterpretation of Corel-generated PDFs. (Also, Corel, since being taken away from its corrupt founder (who, in spite of his evil pillaging of his own company, did create quite an interesting organization with a fantastic range of products IMO), has become quite awful in many respects, and now represents, to a large extent, the nadir of the "feature-matrix" Windows software industry.) However, IMO, CorelDraw still manages to not suck as completely as Adobe CS2 from a usability and reliability standpoint.
I personally prefer to use Windows for my design work, but a number of designers use Macs, and they are justified in using them, for the reasons discussed on this thread. I resent the fact that many people seem to regard designers as being "stupid" to a huge extent. It's almost as annoying as the huge number of people who pay $500 to a high school kid (usually a nephew) to create graphics for them and then deem it to be acceptable graphics design. Alas, being a graphics designer means committing yourself to perpetually walk a trail of tears.
Looks can be a requirement when buying a car. Why can't they be requirements for buying a computer? Because a bunch of uptight, close-minded snobs say so?
Actually, I agree with you on this point also. Aesthetics are a huge factor in all of my computer purchasing decisions. I won't buy a system that doesn't look good (whether its a Mac or a PC). IMO my MacMini is one of the most visually interesting computers ever made (as are my two ThinkPad tablets).
And I'm not the only one who appears to be able to show this kind of restraint. Peter Bright at ArsTechnica recently posted an article about how broken Win32 is and what Apple did right with Mac OS X's development environment.
What irritated the heck out of me in that article is that the author did not touch on .NET. It has been well established since the 1990s that Win32 is a living nightmare of an API. For the past several years, Microsoft has been aggressively touting .NET as the method-of-choice for programming Windows applications. IMO the author's article would have been rather more relevant if it had compared .NET with Cocoa.
