At first time i thought it is pointless effort. MDD,macmini,pbook,g5 pm-s and even overclocked pegasos faster than sam460, so what's the point?

If you wandering about a minute, the answer is simple: os4 has only one advantage nowadays. It is on new (newly produced) hw. Morphos on used mac is good for getting new people who're wanted cheap hw and/or familiar with macs already. But if you have a project for example running an office or controlling embended system, you can't say:

This is our offer, the software will be xxx USD and the hw, the hw some used second hand hw....
