Since you asked for some personal experiences, I'll share my reasons for leaving academia. Basically, I didn't want to have the pressure of writing grants to keep my lab funded. Grant money was getting scarcer and scarcer when I had to make my decision, and it seemed like my thesis advisor was perpetually writing grant applications. He had several grants going, so one of them was always up for renewal, and the pressure was always on. I wrote an application for a fellowship grant myself so I saw how time-consuming the process was, and realized that writing multiple grants is a full-time job.
I didn't want to be in the position of worrying "If this grant doesn't get funded, how will my postdocs feed their babies?" So I took the easy way out and went into industry, where the business-types worry about the money.
Mind you, industry has its own problems, but I don't have to worry about money. If it runs out, it runs out, and I get laid off, which sucks, but at least it isn't on my conscience.
Also, in industry I can tell myself that I'm working on something potentially useful, which I find more motivating than pure research. As you know, research can be immensely frustrating, with weeks or months going by without any useful results, and the idea that there's a new cancer treatment (or whatever) at the end of it kinda helps me not get too discouraged. (Unfortunately, not one project I've worked on in the biotech industry so far has actually turned into a useful drug, but there's always hope for the next project, right?)
