Except you're wrong ....
You can add a second monitor to any of the new iMacs with a $15-20 mini-DVI to VGA (or mini-DVI to DVI) adapter cable that plugs into a little port on the side of it.
I ran a 20" aluminum model this way for a while.
For that matter, any Macbook Pro can handle attaching a second display, and use the built-in LCD in tandem with it, too.
I think some of the rulings in the Microsoft case were nonsensical B.S., actually. They did a lot of questionably legal things, but the courts went after them and punished them for some of the wrong ones. (The big MS issue wasn't the IE bundling, Media Player bundling, or any of that. It was the way they strong-armed companies into only loading and offering Windows on their hardware. You can't legally make an agreement that tells someone you'll sell them your product at a nice discount, ONLY as long as they refuse to sell the competitor's offerings. For that matter, I think their attempts to violate "Right of First Sale" laws by denying people the ability to resell any OEM copies of their software, even if said copies were never opened and used, is a legal violation too.)
I used to think that OS X would be best just running on Macs, but now I'm all for running it on other PCs.
The reason?
The cheapest (and only) mac that can physically handle dual monitors is the Mac Pro which costs at least £1,700. You can buy a dell that has pretty much any dedicated graphics card for £350 that can do the same, and even cheaper if you build it yourself.
Why should we be forced to pay £1350 extra for such a small feature? I bought a Matrox TrippleHead2Go for my MacBook Pro to run dual monitors, it cost £200 and is no where near as good as two independent monitors.
I'm not saying that Apple should licence OS X to Dell, but I am saying that they should allow us to install it on any compatible system without having to torrent a hacked version, just provide basic motherboard support and allow major manufacturers to produce OS X drivers just as they would for Windows.
Microsoft was forced to produce a copy of XP that didn't have Media Player on it, so why is Apple allowed to get away with telling me that I have to spend almost 2 thousand pounds for a basic feature?
