IMHO really no Problem, ok Linux is not Windows so not every Feature is available exact in the same Way as on Linux. But right now I run Linux since around 6 Years and I have for almost all my needs a Linuxsoftware.
With Ubuntu I found my Distribution that is really designed for Enduser.
If you do Linux on Desktop for Business the my proposal is really do it in steps, so you don’t end up with a disaster. Also testing is really essential, integrate your Customer into a beta program and allow feedback.
