I agree with you.
A normal 78 deck is more then enough to learn and have enough variation to give a decent reading.
A lot of good readers don't use reverse card....it's the readers ability that is most important, not how many variation the cards manage to show
As for PC programs and use of reverse card, I will also suggest to turn them off, this because the program don't take into account the influence from the side cards, which also play an important role in a Reading.
The program is a great way to learn Tarot....use it as a Tool.....that is all it is....it can never replace your intuition which is the most important ability in any Reading
