We interrupt our regularly scheduled MacMaineiac column for this important computer purchase advisory. If you’re thinking of buying a MacBook Pro portable computer, or an Apple iMac all-in-one desktop computer, think about delaying your purchase a couple of weeks - at least until June 11th. Here’s why.

Industry sources are starting to buzz about new product announcements at Apple’s Worldwide Developer’s Conference (WWDC), which kicks off with Apple CEO Steve Jobs’ keynote address on June 11th. While WWDC is aimed at software developers, Apple has traditionally taken the opportunity to introduce new hardware as well. Both the MacBook Pro and iMac lines are, by computer standards, getting a little “long in the tooth”, and should be due for some updating.

Tech pundit crystal balls see the new Intel “Santa Rosa” Core 2 Duo processors coming to the MacBook Pro, with faster processors, bigger data busses, and better power consumption. Some believe the iMac will get a slimmer form factor, faster processors, and bigger displays. Here’s one caveat. If you want a 17-inch iMac, to perhaps fit into a snug dorm room space, you’ll need to get it fairly soon as rumor has it that the 17-inch display is soon to be history.

Moving on. I recently heard that a certain host of a certain weekend computer radio program was talking about the state of security on the Mac. As she generally gets just about everything she says about the Mac wrong, and on the remote chance that any of you actually listened to her program, let’s cut through the FUD (fear, uncertainty, and doubt) and get to the facts.

There are still no viruses, spyware, adware, Trojan horses, or any other malware afflicting Macs anywhere “in the wild”. Many pundits chalk this up to the relatively small numbers of Mac users - the “security by anonymity” gambit. They argue that, as more computer users turn from “the Dark Side” and get Macs, more malware will be written to exploit them, and it’ll be only a matter of time before Macs become a growth market for the likes of Symantec and McAfee and others.

A “growth market”? That’s scary. I don’t want to be a growth market. Growth for whom? Symantec, McAfee, and others, that’s whom. So, here’s a question for you. I don’t want to get too Michael Moore-ish here, but has security software become such big business that these companies are finding the holes and charging us to fix them? Yipes.
