One last mail to put this thread 'to bed'... Thanks to everyone who took the time to reply, particularly to those who actually gave me what I asked for, those reluctant beasts, the real-life examples - it's great that you're willing to so fully participate in such a discussion. After all, theory is great; coupled with real-life examples it's even better. Of course, the specific examples can't be applied 1:1 to any other design, as has been said 'x' times, but I, for one, am nevertheless wiser for the experiences that have been shared... I believe I'm a good engineer, but won't stop learning 'till the day I die. It was also good to see that I am not the only one suffering at the hands of less-than-perfect datasheets and the implementation of often contradictoray 'hints' :) - regardless of simulation results and past experiences, it's not always easy when it comes to persuading a customer, who is still convinced that app notes are written by all-knowing beings, to 'do the right thing'.
