Amount of the Pegasos2 systems is pretty limited in da world :) It surely is BIG improvement when the only more obtainable option is EFIKA.

And MacMinis are that powerful level computers, that they will be enough for long time. Like on PC world, 1.5GHz computers are still fine for most things even with their way too bloated OS'es, not everyone are rushing after latest stuff because it's just latest. Or at least there isn't real reasons for that.
