They minified their Flash app from 1 MB to 0.45 MB and don't require user accounts The main selling points of their premium version are user support and access to a desktop version. If they have 'reduced friction' for their online version, the need for support should be negligent and the downloadable version less attractive. As freemium models go, I think thy need to differentiate better.
