Designed to use with their new notebooks?
I'd think they were designed to be monitors, especially since apple doesn't have a non-cinema display (except for those with inbuilt at least), guess you cant get a Mac Pro with a monitor then
The old monitors are still available for the Mac Pro, but I assume they will offer a card with Display Port for the Mac Pro. It isn't difficult to do that.
Still would have been nice to have DVI, but it should be no surprise that Apple went this way. They often break with the past and change standards completely. The don't seem much into extra connectivity either.
Disappointing but expected.
