I can’t claim to be an expert in Saola. Having moved to Hype a few years ago it is clearly my software of choice. Nevertheless, my policy is always to try out the alternatives and keep an open mind.
Being an educator I am also obliged to provide alternatives for my many students who don’t use Macs at home (about 70%). Our college labs are entirely MAC based.
Nevertheless, I am much more comfortable with the Hype interface and feel that it is a more mature program
All said, I personally would never change. I think Hype is by far the best tool out there for its purpose. However, as I’ve said many times in the past, ignoring the Windows user base is ignoring a massive market, and that is great pity as well as a potential financial loss.
