Dan, I stand corrected with your experiences. But those are yours, after you "changed many or my families 6 batteries and numerous friends and neighbors." You are now, "semi-professional." I am speaking of the occasional, one-time and done replacement. I have done only a pair. And i found it a tad challenging even on the second one. Just read the comment section on iFixIt where there is a sample of folks where things went South -- specially after trying their own shortcuts. Let's leave it at this: we just disagree on the level of difficulty for the amateur. No sense beating this to death.
