I'm thinking of buying a netbook, but I wan't to install mac leopard on it, wenn I saw the dell mini 12, I thought: maybe it can run mac leopard because the dell mini 9 can do it to. So, is it possible? and do I need a retail DVD (which costs money, doesn't it?) when I wan't to install it? And if it's impossible, which one do you recommend me then (please not to expensive) and do I always need a official retail DVD to get it working?
