I have one specific piece of software I need to run (a security DVR camera viewer) and haven't found a replacement in linux. I used to be full-time linux, and I would still have one linux-only PC (and another for gaming) if not for this specific problem. FWIW I have messed with all the common and many of the uncommon linux security camera software, and none seem compatible with my particular DVR. I will eventually replace the system with another, but that's quite an annoyance.
