So, stop down to about f/8 and you will get a DOF of about 8-10 inches.

Now, you have to ask yourself why did you spend so much money for a f/1.8 lens when you really can't use it wide open for the types of photo's you want to shoot!

Yeah, thats what I am asking myself now

Yes - just get a P&S - no probs with DOF there!

Or stop down the lens, same results. This is not a "problem"

There are some situations where you can't stop down. Like where you need a faster shutter speed to avoid subject motion blur, e.g. father/daughter waltz at a wedding.

You can always stop the FF down 2 stops compared to your beloved m43.

Ok, now what just happened to your shutter speed?

Went from 1/125 to 1/30 sec., didn't it?

What if 1/30 isn't fast enough?

The "problem" is that you are paying a lot of money for a fast aperture that is usable only in very rare circumstances.

Nonsense. I use sub-f/2 all the time. And I manual focus. And I get very good hitrate. I love to have that option.

Sigh, see above.

I think a lot of beginning photographers get "suckered" into paying a lot of $$ for a really fast lens when an f/2.8 lens of the same model would cost a lot less and work just as well in the real world.

This is of course just your opinion, and often wildly wrong. I am beginning to feel that you were "sueckered" into m43 and now feel you have to defend your purchase by belittleing other systems and people who buy them.

Sigh, see above.

Lots of people like to use at apertures not achievable on m43 - loads of perfectly fine images prove that all over the internet.

It is worth spending a bit of time checking what your lens can do wide open and stopped down a touch. But as pointed out elsewhere the focus confirmation can kick in sooner than you think and not necessarily on what you thought it focussed on. Use static subjects and if you haven't got a tripod then find something to stand the camera on and use a time delay.

Also double check your technique. Need to be very precise and steady.
