Hi,
I guess there will be a lot of frustrated beginners wrecking Dues.
As for applications for the Due, I have in mind a psuedo modular synth - lots of oscillators, wavetables, analog inputs, some sort of low tech interface and a simulated patch panel.
16 bit audio should be very fast in a 32 bit mcu leaving enough cpu to implement the connections in the simulated patch panel for real in software.
