Don't be too sure. This is a bare bones system. Wally World is selling a 2.4 gHz WinTel system from HP that includes OS, an Office Suit (Not Microsoft), modem, nic, kb, mouse, speakers and a 15" LCD flat panel for $469!
The Mac world is all over this as a great deal, but the real world will just see a system that still needs hundreds of dollars yet to make it useful.
Not knocking Mac's, they make good systems and have many advantages, but a good price still isn't one of them.
This reminds me of those "net only" computers that Ellison came up with. Since they were not complete systems, Oracle sold them at bargain prices -- finally giving them away to schools.
