I used Windows for a long time before ever getting near a mac, through college and work etc. But a mac was the first computer I ever personally owned, when I set up a home recording studio I went for mac partly because the people I worked with used them and partly because of the supposed ease to set things up compared to a windows computer. Now I can't see myself ever owning a Windows PC, this mac does everything that I need it to do, easily and just feels more 'fun' to use than Windows ever did (though i know that was in a totally different environment).
The more i learn about it, and the Leopard update in particular just blew me away, the more I love it.
