Ah, but the lab doesn’t use Windows, do they!
I'm just telling you about the problem with Windows platform, in that they have over 100,000 viruses, which the Macintosh computers don't have -- but that a Macintosh user can be of help to those Windows machines and "help them out" -- when they get infected -- even if the Mac OS X never does get virus infections.
Macintosh users don't have the problem, but Windows users do have the problem.
Any other platform doesn't matter to me (even though they matter to a very small segment of others), because for the general public/consumer, all you're dealing with is Windows and Macintosh and that's it (even though the Mac OS X is UNIX underneath, but the general consumer doesn't deal with that). Where the sales are at with the consumer is Macintosh and Windows. And where they're concerned, Macintosh doesn't have the problem with viruses like Windows does.
Outside of Macintosh and Windows, the consumer doesn't care about anything else, and there's no mass market outside of that.
Actually, in the business world Linux/Unix is resurging due to security concerns.
Lots of commercial offerings coming up this year.
Mac’s big installed base is in publishing, and graphics arts. They surrendered the engineering market in the early ‘90s when they gave up on claris CAD. Had they hung on for 3 more years AutoCAD 13’s flop with DCA might have tilted things differently. The cost of software is always greater than hardware in engineering.
Just remember, the original “Internet Worm” was a Unix Program.
