One feature I really liked and continued to benefit from was the "Play It!" section. I could go through at the native level at full speed and improvise the conversation as I went along. It was like having a real conversation with a native speaker. Now with the way the system works, it's slow and lockstep (i.e., the system has to recognize what you say before moving on to the next phrase) - so no longer useable for me.
While the new approach may have value to someone just starting out, I think it takes away much of the value of what is a very clever / innovative learning technique.
