They don't crash or have viruses this is true.
I personally tell all my friends to buy a Dell but then I make the mistake of letting them use my 17" Powerbook.
I am going to get one of these Mac minis for my living room but I'll probably wait and see what the next update is and then either buy the older model discounted or pickup the newer whatever. Also if I wait until this spring I'll get Tiger with it. Mac OS does not have serial numbers so there is nothing stopping someone from using the installer to install it on whatever you feel like, not that you are suppose to do this. lol
