Definitely valid consideration. In data acquisition the scope
of what we must provide is very small, but still we use some
big commerial tools, FEMLAB (electric and magnetic finite element
simulations), assorted FPGA compilers (Altera, Xilinx),
and they all seem to work ok on both centos and ubuntu. Some other
major tools, SolidWorks (3D mechanical design), Altium (PCB design),
do not run on Linux at all (any Linux), so those people are
suck with Windows laptops and desktops.
Also luckily, our stuff does not need to be qualified or certified,
so as long as things work and lights blink and data flows, all is good.
Actually, for vendor support, I see a consolidation on Debian-based Linux,
RaspberryPi comes with Debian based OS, Nanopi seems to be Ubuntu, Phidget
toys come with Debian drivers, a brand new board with Xilinx FPGA just arrived
in the mail, also runs ARM Debian. If not Debian, then it is a custom rolled userland,
often based on busybox. No RedHat/Centos/Fedora anywhere in sight.

Seconded. Certainly carried us through what, 15 years of worry free
and trouble free Linux OS? Yup, since SL3 in 2005 on our first 64-bit AMD Opteron
machines, until 2020 today.
