Everybody's got the spreadsheet and word processor - I'm talking about mission-critical apps specific to my business, which don't even exist for the Mac, much less *nix platforms. They're certified for Win2k Pro and WinXP Pro, period. And those are two fine, stable platforms for our needs, with no hassles trying to track down obscure drivers or utilities.
For those with less stringent requirements, I'm all for Open Source, *nix etc. and I've been futzing with various OSes since I learned what Hollerith characters were. But like I tell the Macmoonies . . . . I'm not shopping for a new religion.
My experience is these new Linux/open source fruits are the biggest zealots the industry has ever seen. Novell thought they could ride their "movement" into some profits, but what they forgot was most of the open sourcers don't like to ever actually pay for anything.
In the end, not much has changed, *nix continues to further fragment and cannibalize its own, an endless confusing mess that allows Microsoft to stumble to record profits every quarter.
