Until I got the Hoverfly quad in the air I never used an OSD. Granted the OSD functionality on the HF board is pretty minimal at the moment but it's nice to have battery voltage and altitude visible when flying FPV. A couple times I've found myself amazed to see the altitude at 200 feet or more, it's really hard to judge things like that when flying with tthe goggles on.
The next firmware release for the Hoverfly board should have some OSD enhancments and as soon as they release the GPS module there will be even more. Once I get the new release I'll record a flight and post it here for comparison to some of the better more established OSD products out there. For a feature that's embedded in the board at no extra cost it does fairly well though it's not up to the standards of something like and EPI board.
