Only among pencil-necked geeks.
Amongst the world's poor as well. That includes entire nations like India and Russia with huge pools of programming talent who simply cannot afford to be sending Gates and Co. an extra two hundred dollars every time they turn around.
Also amongst people who require robust and reliable software. LINUX can run for years without crashing; Win 2000 appears to be able to go for more than a few days without the blue screen, but it's a case of too little, too late. Moreover I actually do hear of cases of people replacing Solaris machines with LINUX machines simply for the greater reliability.
Sounds like the info I had on LINUX and the Mac was a bit dated; I'd assumed the situation would not change. I'd be curious to hear how they deal with all the LINUX software which uses three mouse buttons...
They buy a new mouse.
Too bad for them.
They cannot afford the best software.
Oh well, that means we'll keep our competitive edge for awhile.
