It is a wonderful system, but it does not support all the latest features. For example, one can't use HW performance counters on SMP kernels even in the new NetBSD 3. The FBSD6 now also supports fine-grained locking in the kernel, another feature that NetBSD is lacking (so it works less than optimal on SMP machines). Therefore, I'll probably switch to FreeBSD for my research purposes.
