I remember reading a while back that the dutch went open source a few years back, not quite sure of any more detail i cant remember. I know some schools in the USA like Linux too, and at our Uni we have a fair few Solaris machines as well as SUSE.
For most people, linux would be the same as windows, all my family use a pc for is wordprecessing and card games, linux can provide that, and it would make buying a pc £60 cheaper.
I have used Linux on and off, i cant use it too much as most things i use are made for MAC or Windows. To my way of thinking, MAC Apps should run on Linux as i am sure BSD is more or less the same thing.
M$ Will never be short of orders, too many things depend on it, there are atms that run windows 2000, and some we all know run XP as 200 went a little mad some time back and random ones gave extra cash out.
I would like to see a really good attempt at Linix for the Windows user. Linux is beyond most people, just because its so different in ways, longer boot-up, different file structure, etc. Lindows, Linspire was supposed ot bridge the gap, but i recon SUSE or Madrake are easier than Linspire.
Oh and most people will never get to grips that you will have to look on the box when buying games to see if it supports the OS. I have had so many people in the past buy Windows games and moan because they wont install on an Apple. But if business starts to go Linux more, then staff get used to linux, and the ones that dont play games (unless its cards/mine sweeper,etc) will adapt it for the cost saving and be nice and happy they have saved £60 or so on there desktop. I notice HP will now cut the price if you want Linux, FREEDOS, and no OS on some of the range online.
