Switching point at VDD/2 will give you also equal rise and fall times for the outout.

if you switch from vdd to vdd/2 will affect on your signal amplitude not on rise time fall time.

There is no need actually to set inverter's switch point to VDD/2.

Re: why vdd/2

it would get max noise margin,both low noise limit and high noise limit.
Actually ,you needn't do it because it will be a big P/N ratio.
