Obviously, I should be disabling the IS when I'm shooting with a tripod, but what about if I'm shooting at a high shutter speed? Does IS become a hindrance at those speeds? If so, about what speed is it safe to shut off the IS?

Should I be disabling image stabilisation on the OMD when shooting at high shutter speeds?

I don't bother. Seems to be ok for me.

Like Mjankor, I have noticed no ill effects of keeping IBIS on at high speeds so I do not bother to turn it off.
The shutter speed at which IBIS stops being of much help (without doing any harm) depends on the focal length used. The general rule of thumb is that you should be able to handhold a speed of 1/EFL without stabilization, where EFL is the FF-equivalent focal length. For MFT, EFL = 2 x FL, so for example at a focal length of 25 mm, the rule would say you should be able to manage 1 / (2 x 25) = 1/50.
But this is only a rule of thumb that depends on individual capabilities as well as shooting conditions. Furthermore, many say that the 1/EFL rule is too generous and should be more like 1 / (2 x EFL). On top of that every handheld shot contains an element of chance. So I would say that IBIS remains helpful quite a bit beyond the point that the 1/EFL rule would suggest.

Even if I'm shooting at a fast shutter speed, I find the IS helpful in stabilizing the VF image.
So like others, I'll only turn it off if I'm using tripod (although I have accidentally shot the occasional long exposure w IS on, and didn't notice any ill effect... other than the hum until the shutter closed.

Perhaps Olympus can implement some form of 'Auto IBIS', kind of like 'Auto ISO'? Based on the lens' electronic signature and shooting parameters, the camera can then automatically switch IS on or off for the best results. Of course, their crazy menus should allow users to set the limits of this behavior...
I have done a lot of pictures with my OM-D and meanwhile a leave the IBIS ON all the time:
- With shutter speed faster than 1/200 the IBIS should not hurt
- With 1/50 to 1/200 some people have "shutter shock", I have tried to reproduce it with different lenses but my camera does not do it ...
- Below 1/50 IBIS is the only way to reduce blurriness
- On my tripod (I have a long and lightweight Velbon 53d) the IBIS can help to reduce accidental tripod vibrations. I don't see any problems with my long exposures even when shooting stars at 3-30secs

I didn't even turn it off when on a tripod. Do you need to?

The instructions state that you should.
Depends on the lens your using. Depends if you are panning at the same time for the IS to catch up. It also depends how steady you are. Everyone has become so dependent on stabilization where it does not matter. I think it's because the smaller cameras are harder to hold. A camera with some weight has advantages.

If you are holding a camera up to your eye for any longer than a minute or so, I think you will find that most people will shake more with the heavier camera than with a lighter camera. Particularly as they get older

+2. I never turn mine off.

Thanks. I've only ever used in-lens stabalisation before. I should read those instructions more carefully.
Does it also explain the difference between IS1, IS2 and IS3 ?

I only turn it on when it is needed. Not sure it hurts, but would not remember to turn it off when using a tripod, and it does hurt then. Also no doubt it consumes more battery when it is on.

I did a test a few days ago with 75-300mm and E-M5 on tripod 2 sec self timer plus 2 sec shutter shock delay. Shot IS = 0, 1, 2 ,4 five set of each. I couldn't see any difference in sharpness in any of the shots.

Invest in a quality tripod or mono-pod it will make a world of difference.

Well a good tripod generally makes any shot sharper but the much of the attractiveness of m4/3 is small, light, compact and portable. Also a lot of animals just don't wait for you to set up a tripod.

Well, I am certain the battery last longer. Since I never have it on for the tripod, I have nothing to compare. As others have said, Olympus recommends turning off IS on a tripod. Other camera manufacturers agree.

Power consumption will be pretty much the same with IBIS off as with IBIS on. Turning IBIS off does not mean that you turn the power to the IBIS system off. The system needs power even when it is turned off. Otherwise, the sensor would be out of position. See here for details:
