I think there is no real difference from before ? The third party licensed stuff (Android emulation, predictive typing, Exchange, etc.) never was on the image & you installed it from the stor on first start.

The only thing which changed is that you can now get the image before first buying a Sailfish X license.

In any case I really like the trial program, as it yet again lowers the barriers for entry - if you have an Xperia X/X compact (patched image)/XA2 you can just try most of the system out without having to shell out for a license first, which should help to bring more of the hesitating future Sailfish OS users on board.
