That is a load of crap.  If you don't like Linux, don't run it, but let's
not push opinions here.  You want the truth about what Linux is capable
of, then you do the homework and contact IBM, Compaq, and HP and
ask.  They are giving Linux their full support and cooperation and for
some very viable, well thought out and good reasons.  It's a good OS that
has come a long way in an extremely short time frame.  It has considerable
promise.
Now if you really want to do some NetBSD work on those systems, that would
be quite cool as well!  NetBSD is an awsome OS and deserves it's own
attention.
