This is a great question for future upgrading. Does the above mean that any of the newer iMacs and Minis can do this? Does it work with Thunderbolt, too?
I've been thinking about getting an iMac, but have been worried about the fact that I wouldn't be able to upgrade either the CPU or GPU a few years down the line. This could be the solution (okay, not perfect, but it would be cheaper than buying a new iMac every few years...)!
I guess another question is how much of a pain would it be to run a setup like this? Would it be possible to make the iMac screen the Mini's default option?
Thanks for any more insights!
