Whether a kernel is good for user interfaces has less to do with how the parts
of
the kernel are organized (mono, modules or micro) and more to do with threading,
scheduling, resource management, etc. Threading, thread priorities (and
low latencies in the media kit?) is where BeOS had an advantage over the
other systems, back in the days - not in being this-or-that kind of kernel.
Unless I am mistaken, all of the major desktop operating systems are modular
hybrids these days, including Haiku, and they are nowhere near being
microkernels.
Neither was BeOS.
A hybrid kernel is closer to the monolithic kernel than to the micro kernel.
There is no value judgment in either monolithic or micro. They're just
different approaches
to system design. A matter of taste, if you will. And Haiku is pretty nice
regardless.
