Of course there is, lots of software doesn't work on Linux. I've switched to using Linux on my personal laptop, but I can't recommend it to anyone else in my small company (we're not a tech company, if I did get anyone else running it that would immediately make me their tech support, and I'm not doing that), and I can't use it on any of our branch machines as the POS software only runs on Windows or Android (might switch to touchscreen Android kiosks in the future though).
