In my experience power users don't want SaaS. They tend to want control over their data, they want control over how/when the software runs, they want things to work offline, and they care about their privacy. It's the people who don't know/care about tech and just want a magical black box that love SaaS. They want all the complicated tech stuff to be someone else's problem, and they'll pay over and over and over again just so that they don't have to think about or manage anything.
Yes, exactly. SaaS tends to repel power users because it's so depriving of control. Just my experience, but the main people who pay for SaaS are usually those who don't want to invest time/effort into learning/customizing something, they just want to pay and be done. An exception to this is platform SaaS that targets tech companies. Those can be hit or miss.
