The only place where Unix is losing ground to NT is the workstation market.
NT makes a modest workgroup server, and a worthless enterprise server
(despite what Microsoft would tell you). Unix still has a stranglehold on
the mid- to high-end server market. The current NT kernel performs well for
workstation apps, but poorly for most server apps due to design limitations.

The problem with the NT kernel is that certain important aspects are
single-threaded through CPU 0, such as I/O. That means that NT threading is
only applicable to user space computation, such as rendering. This is also
the reason NT scales poorly for things like database applications.
Linux has a similar problem in the current SMP release (only one kernel
lock), but is being corrected as we speak.

I am hesitant to agree with this, but in a general sense you may be correct.

Not to mention the proliferation of non-standard Unix "standards".
