Or you buy the older and still available Apple LED Cinema Display.
And knowingly spend the same amount of money on product that contains inferior camera and no possibility of ever using Thunderbolt in the future?
It seems clear that Thunderbolt display is meant to be used only for the brand new Macs. If you try to purchase just the display, shipping time is 6 - 8 weeks. If you add TB display to your new Mac Mini order, it ships in a couple of days.
