What I really love is the fact that the PowerMacs in question are FAR slower than a cheap bargain basement x86 box, which can run AROS.
So what if 30 Power Macs can be bought for one X1000? You can get a much faster x86 for the same price, and AROS has just as much to do with AmigaOS 4 as MorphOS does - i.e. none at all.
So if you're going to buy an NG system and don't want to buy an X1000, then get an x86 box and run AROS. But if you want to run AmigaOS 4, then it can't be a PowerMac so there's no point whatsoever mentioning it.
Stupid thing is that this MorphOS evangelism every time OS4 is mentioned has done far more damage to the MOS reputation than both AROS and AmigaOS put together.
