I had a stability issue two or three releases back (1.7.?). The program did seem to unexpectedly quit pretty often. I sent a description to AM at the time this was a problem for me. They asnwered my emails made some suggestions that improved stability. The next releasemy stability problem was fixed.

I use the program daily. I abuse the program by asking it to do exports for web pages. I keep my advising and consulting notes in it. These includes video, links, audio notes from my iPod voice notes, photos and other graphics.

It has been a very useful program for me as a professor. I hope it continues to evolve and improve. BTW, I run it on my laptop and on my desktop machines. It is very stable on both.
