Ahhhh.. but Paolo.. you seem to be a fairly modest guy despite your accomplishments.  There is a difference between someone who uses a mac or has a need for linux.. and the other breed of Max/Linux "user" that usually devolves down to ego.  When they start selling mac parts on the open market that are as easy to assemble as my pc; I might actually convert.  I started on a mac 2e waaaaaaaay back in the early 90's(first puter ever was a trs-80 that I bought in a kit at radio shack).  I went to pc's when I discovered that I love building computers almost as much as I like using them.  My brother in law who ows a computer shop is a big linux user; he's ALWAYS having to tinker with his computer to get it to do what he wants it to do.  Me?  I've had to crack the case on this box once in the last couple years and that was only to do a voluntary upgrade on my vid card.  I like to sit down and start doing things right away on my computer AND manage to have a few spare dollars in my wallet.. mac and linux won't let me do that.
