I do it every week or two.
Upgrading from 10.2 to 10.3 required a reboot _during the upgrade_ on two machines, two reboots on a third.
One of the main reasons I switched from FreeBSD to Debian (crap, it's been over a decade now!) was the lack of flash on FreeBSD. With that having become a non-issue, I keep thinking about switching back, but... inertia.
(or, if it ain't broke, don't fix it)
