Are you able to watch Netflix with Chrome (I assume its actually Chromium?) on OpenBSD? Last time I checked Widevine wasn't supported on OpenBSD.

Force HW acceleration in Chromium (about:flags) and tweak a bit the /etc/login.conf (cap_mkdb /etc/login.conf as root after editing).
* Hardware support is great for me because I use a Thinkpad: most OBSD devs use Thinkpads as their laptops. I tried on a work-issued Dell and the driver support wasn't there + some odd kernel panics happened. Target "current generation - 1" and you'll likely have less to worry about.
* Expect performance to take a hit – every so often Chrome exhibits graphical tearing, slows down, etc. The pages I frequent don't tend to cause this issue, but if your browsing is JS to the max you might have some headaches.
* You'll find tons of packages, but should expect support to be lagging behind Linux. Just a function of adoption, really. Additionally, OBSD compiles some packages with security functionality that isn't present in other OSes, so expect a SIGABRT or two that you might otherwise not see.
Really though, it depends on your needs. It fits mine perfectly.
