A SaaS solution should have little, if any, impact on price and has real advantages -- hardware & OS agnosticism (Mac, PC, Chromebook, Android, IOS, Solaris, NeXT, Lisa -- ok maybe not), truly portable, zero-cost updating, zero-install for the customer, ability to collect usage metrics, and for the publisher a long term revenue stream. We're definitely going to buy the LQ version but I'd gladly pay $20 / month forever so we can run it on our Chromebooks throughout the facility.
