I suspect MorphOS for the Mac Mini comes around Easter 2009.
There will be another release (V2.2) probably still this year, but it'll be exclusively for for Pegasos & Efika.
Frank Mariak (core team member) confirmed in early autumn that the release for Mac Mini will come as soon as possible (audio driver and network driver is still missing).
I'd gor for that, unless you have some funds available to spend for fun projects like the Efika (and I *have* fun with mine) or Sam (which has a quite better performance than the Efika but requires some *serious* funds). Alternatively you may go for a used Pegasos, you have to keep your eyes open, but they are offered from time to time for reasonable prices (less than a Sam and much more powerful).
