Bob Palais wrote an excellent article back in 2001. But the arguments that I've seen favoring Tau over Pi were basically a matter of style and taste.

What would the adoption of tau do to:

1. The Taylor series for trig functions, such as:

2. The relationships between trig and hyperbolic functions, such as:

cosh(ix) = cos(x)
