I fly the big birds, and Ive been using PFMA for the last couple of weeks. Its real intuitive for me (dont understand the one star reviewer that couldnt use it...). The fact is that I own other e6b calculators, and PFMA interface is much more simple and fun to use. Besides it is a very good learning tool for any wannabe airline pilot since it has the same basic interface as boeing and airbus flight management computers. Hope to see weather and w&b in the future, sure it has the potential. Meantime I ll continue using Aeroweather (great free weather tool) and PFMA for my daily calculations.
