I think you are right for what concerns the speed of the calculations, however 
   don't underestimate the advantage of getting rid of the solvent noise, 
degrees of freedom and viscosity. Eliminating solvent viscosity could speed up 
considerably large conformation changes and eliminating solvent noise and 
degrees of freedom is extremely helpful for scripts that exploit 
parallelization in a parallel tempering scheme.
Since this is my case :-)), I am really looking forward for this new release!
Bye,

Stefano
