The Mac Mini decision is a good _short term_ strategy. Long term, it's a dead end. Using it MorphOS can grow a user base -- whereas the X1000 will probably go nowhere -- and if MorphOS is wise, they'll use the larger user base to move into newer hardware when they're ready.
Of course, as a strategy, I doubt it will beat AROS, since AROS gets users more powerful, less expensive hardware that will grow with the future. MorphOS' strategy will last only as long as the Mac Minis last.
My two cents.
