Microsoft has made it's niche, to be sure. I am futzing about with a Mac and trying to see if it has the capability to work in a Windows network environment, as I am seeing that a totally Mac network environment would be too costly. I am not feeling the love...
One of the things that will make it easier for Windows users to move to other platforms is MS's penchant for forcing users to "upgrade away" from working and productive products(like Microsoft Picture It! Publishing Platinum - the only reason I have to keep a machine running XP).
