You can connect to your existing PC monitor or buy a second one if you want to. This Mac is intended as a second household computer. It might be find for the kids' room or the family bedroom.
Sure, but its not a $499 computer. If they lowered the price by $100 but did not include a mouse or keyboard (of course, you can use old ones) a hard disk drive (you can use an old one) or the little fan that keeps it cool inside (you can always stick your own fan in there) would you say that they are selling a $399 computer?
