I run OpenBSD on an ancient laptop that I use to play videos. In about 7 years, I have had no bad experiences with it. Upgrading from release to release has been painless, hardware support is fine. Playing HD videos is out of the question, but the laptop is from ~2008, and it wasn't a high end model back in the day, so there is little OpenBSD can do about that. I cannot say much about security, but in terms of reliability, I have only good things to say about the system. EDIT: Once you connect a device to the Internet and possibly install third-party software on it, your own expertise is likely to have a bigger impact on security than the underlying system. I am not recommending to NOT use OpenBSD, but if you have no prior experience with it, you might have a better experience using what you know.
