In what sense the Powerbook and G5 macs are not underpowered custom high priced hw?
So if you buy Sam, you pay for AmigaOS 4.... What's so bad about it? When you buy Powerbook and G5 macs you are paying for MacOS X, or not? Can you buy a Mac without Apple's OS price attached to it?
The difference is that Steve Jobs never tried to promote his OS by declaring Morphos illegal. I sincerely doubt that the Morphos team would like to line Ben's pockets by supporting a machine that has to be bought with his OS.
