Hmm Ben IS a beginner in OS-development and I fail to see what
my funny remark has to do with MorphOS (other than paranoia).
But since you have asked ...
a) MorphOS has been started far earlier than Hyperion-OS4,
and is allready working (but not finished), so that proove
that they can write a full blown OS, ergo no beginners.
You could also see the PuP-kernel as an mini-OS, since it has
all the main features that a kernel needs.
Again this was clearly a joke !!
You should also remember that the OS is not done by Ben himself
(thank god), but by his employees, and that every time Ben
gets "technical" on ann.lu, hilarious fun is secured (/me just
remember his Intui-68k = Intui-PPC speeches).
Ben may be good at making deals, and he's damn good at stiring
the masses (marketing), but he is no developer.
