From their site:

NetBSD is a free, secure, and highly portable Unix-like Open Source operating system available for many platforms, from large-scale server systems to powerful desktop systems to handheld and embedded devices. Its clean design and advanced features make it excellent in both production and research environments, and the source code is freely available under a business-friendly license. NetBSD is developed and supported by a large and vivid international community. Many applications are easily available through pkgsrc, the NetBSD Packages Collection.

That’s all true!

NetBSD is the only BSD system that I’m still willing to consider using – I’m mostly giving up on BSD – but still has some glitches.

My main issue was lack of easy availability of binary packages. I was tired of struggling with FreeBSD’s packages and ports interactions, and wanted something easier. pkgsrc is really nice – better than ports, I think – but still has problems. pkgjam is a better solution – with luck it will become popular. Because none of NetBSD’s mirrors seem to “carry” the binary packages, and NetBSD’s main server is flaky and overloaded, using it for a desktop seemed beyond my pain threshold.

I’m running Arch Linux now, but keeping NetBSD in reserve.
