that may be so, but how many people out there know how to push qnx that hard compared freebsd/linux on amd64 compatible hardware, and how many people know how to configure up a juniper mx or cisco asr9k, compared to the number that can tune a freely available unix. As someone pointed out elsewhere, there's no such thing as a free lunch. If you want to economise on hardware, you should expect to pay for the expertise to do it. Nick
