Unlike Macmini this one has powerbutton where it belongs, and it even has eject-button for discs. Add to that it has a nice aluminiumcovers instead of sperm colored plastic, and hey, lets not forget it has more than two usb-ports too. This case is about a thousand times better compared to what Macmini has.
And the Mac has OSX while the "Amiga" uses a Linux distro.
I don't even like OSX that much, but I'd still rather have the Mac.
Of course it does have a Blu-Ray drive. Apple hasn't gotten around to embracing those yet.
