Hi, I'm looking at getting a used mac mini to be my media centre because I think it's a little more versatile than the current Apple TV. I've got a line on a couple in my area but my question is, do I need an intel based mini or can I get by with the G4 1.42 Ghz version. Are the differences minimal based on what I want to do with it (surf the web, email, watch videos listen to music)? Or is the G4 version not worth the $100 in savings? thanks in advance, b.
