Homebrew PCBs

Hi,

What do people see as the pros/cons of copper pours in board artwork?

For mainly digital circuits with small amounts of analog sampling, do
they offer any significant improvement in electrical performance?

I tried a couple of boards with GND copper pour.

For me, all I've noticed is that they make my etchant last a little
longer, but increase the time taken in removing backing paper, and make
the soldering phase slightly less comfortable.

Cheers
David
