[sdiy] PWM or DAC better for audio out?

Can anyone give a good practical tradeoff analysis for choosing PWM vs DAC for 
digital audio output?

When considering how to output audio from an FPGA synth, PWM is so simple and 
cheap compared to a DAC.  I personally can't think of any reason to use a DAC 
over PWM but my hunch is that I'm missing something obvious.
