Technically, the difference is whether or not you fix the thing.  
Realistically, MTBF is mostly used incorrectly to refer to MTTF.  
Shouldn't be, but is.  People that know what they're talking about 
obviously don't have the problem.  So, yeah, we can be pedantic, but 
what it should be and what it is are two different things in this case.  
Sort of like MDT/MST in time.  Most (not nearly all) people use them for 
the same thing, and often incorrectly.

Again, I /totally/ concede that they're different, in the repair/replace 
detail.  You know that, and I know that, but most people don't.  Now 
PLUG knows, though.

There will be a quiz.  Happy Friday!
