I believe the ACD is a sign.
I know i'm taking my life into my hands by posting this but....
I agree with many that the signs are there..... if you're open minded enough to look.
The new 24" ACD has some strange features if as currently advertised it is built only as a Notebook display.
Why the iSight ? all Mac laptops have one.
I believe that the new mini will have mag safe power supply, same as the macbooks, and will use the screen as a selling partner in a bundle if required. adding iSight, speakers and additional ports.
In this type of package it also allows for the fabled xmac, as a stand alone it could be cheaper than the iMac, with equal or slighly higher spec for those that already have a nice display, with the display it would be better than the imac interms of user upgradeability for those that want to buy both together, but cheaper than the mac pros for those of us that really dont need them.
Home users want the ability to add HDD space and upgrade VGA cards occasionally, take it from someone that knows, an iMac with 2 USB drives hanging off it is not a pretty site :-(
