I am pretty sure the Mac Mini can support mobile quad core cpu, pending they get the air flow right. I say this because there a few mini pc from Shuttle and various other PC manufactures that have tri-core(AMD) and quad core machine(Intel and AMD) in a form factor that is a little larger than the Mini. Hell, I think some of them are even using core 2 quad desktop cpu when they were new. I personally would love a quad core(tri-core would also do) Mac Mini to go along with a nvidia quad core based tablet. I don't need extras the iMac offers as I kind of prefer a desktop vs an AIO.
