That's a bit paranoid and overly cautious imho. For starters, powering it off doesn't remove the current. You would need to remove the battery and any axillary batteries. You would also need to remove the lens as there is still current between the lens and the body. That level of condensation is nearly impossible to achieve unless it was really cold and the house very hot and humid. I live in Bangkok where it hits 41c and have went from AC (24c) to out outside (and vice versa) and have never seen condensation.

I think Chuck Westfall had a write up a while back about sleep mode stating it was pretty close to powering it off from a consumption perspective.

For me, I turn it on when leaving for a shoot or walking around. Once I'm done for the night (shooting, post processing, etc..) I shut it back off. I'm not worried about a switch or anything, just saving a bit of battery life. The sensor cleaning is a bit of a plus too, but not really a concern.

Its no big deal. I just turn it off if I see my glasses or the lens mist up :)

It is actually a good idea to switch the camera off when putting it in your bag. Pressed in there or jiggling around, the shutter button may get pressed, half-way starting AF and IS cycles, all the way releasing the shutter, especially if the lens is switched to MF.

Flew to Spain a couple of months ago with a tightly stuffed bag. Heard this funny noise now and again, thought somebody was shooting, but didn't see anybody doing it. When I opened the bag in the hotel room, one body was fine and switched off, the other was switched on but with dead batteries. Luckily I had the other body, but really wanted the one that was dead. Waiting for a battery to charge is like watching grass grow.

I once had the camera in the off position and went to quickly take a shot, to discover that the camera was off. Well, since then, I've never turned it off again.

I can't remember the last time my camera remained in the off position. I only cycle the on/off every now and then to do a sensor cleaning. Otherwise, the camera remains on whether it's in use (duh) or in my bag, if I'm changing lenses or batteries or even removing/adding the grip.

No ills yet.

After reading this thread, I think I'm going to have to re-evaluate my obsessive habit of powering off the camera if I'm not going to be using it in the next 10 or 15 min. I always did wonder if frequent sensor cleaning was hard on the camera - I guess if I just wait to turn it off before it goes back in the bag then I won't have to think about that anymore.

I think this very interesting thread has shown that it really is a matter of choice....

1) Some power-off, out of habit when putting their camera away.

2) Some NEVER power-off, so that the camera is always "ready for action!"

3) Some (like me) power-off-power-on when they've done a few lens changes, to do some sensor cleaning.

4) Some do whatever they feel, as and when......

And NOBODY reports any problems with power switches, or anything else.

So maybe broken power switches is a problem for a tiny minority, and we should just get out there and take more pictures.....

- The lens power pins are always on, whether the switch is turned on or off.
- When you open the CF door it cuts the power, so no reason to touch the switch.
- When you open the battery door it cuts the power, no need to touch the switch.

Only reason for the switch is to disable the buttons and give you a free sensor clean.

THIS!

I've never turned the 20D off!! Can't remember ever :)

With the 7D, I do it every 2-3 weeks for the sensor clean to do its thing....

It's usually on Auto Off after 2 minutes. But...
If your lens has IS, it's a good idea to turn the camera off when you change lenses.

The manual says "The image stabilizer operates for about two seconds even when your finger is off the shutter button. Do not remove the lens while the stabilizer is in operation." No mention of switching the camera off.

...but unless you remove the battery(ies), power remains always on the lens power pins whether the switch is switched off or not. So while it may take the two seconds to turn the power switch off that the IS needs to complete its cycle, turning the switch off will not otherwise be of any use other than preventing you from touching the shutter button and setting off another round of IS. :D
