Hello IO540,
I just checked in my first log book the last sim I "flew", it was an ATC 810 almost 20 years ago when I was doing my Multi IFR. The last time I flew behind an IO540 it was bolted on a Pitts S2B. The reason for that is that my plane doesn't have inverted oil and fuel and I wanted to practice inverted spins. So if you want to allude that I am not a pilot I could care less.
If you are a proponent of electronic flight aids good for you. I see nothing wrong with them. I do see something wrong with guys who depend on them to a degree that they have lost the ability to fly without them.
