This is a bizarre complaint. There are more Mac users than Linux users but still far fewer than Windows users. As such, there are so many examples of hardware and software that are incompatible with Mac. Our IT dude keeps telling me to switch to Windows because of better support from third party vendors.
My comment was specifically about the HP dock. I have nothing for or against Linux as I have never used it, don't know anybody who uses it, and I have no plans to use it. I am simply not qualified to comment on Linux.
