Yeah, there are pro's and con's to both platforms; but even as a die-hard PC user I gotta admit that's one area where Mac rules - maybe partly because us "po people" are usually stuck with PC's, and most likely to perpetrate viruses in a pathetic attempt to "get back" at whoever the original target was...
My original beef with mac was that I thought all the big-wigs there were arrogant bastards and wouldn't contribute to their wealth (then I found out more of what "Billy G" was like

) - also, it's only been in the last few year that macs have gotten less than twice the price for the equivalent computing power, and there is STILL nowhere NEAR the range of software available for the mac platform.
My son (graphic designer) uses mainly macs, and uses Virtual PC for PC apps with good success; so at least the software limitations are less these days; on the cost thing, I fronted the $$$ for a system a few years ago that, had it been a PC, would have cost around $2k instead of $5k, but I know it's gotten closer now.
Still, from a practical viewpoint it's hard to argue with peace of mind, or to put a price on it... Steve
