Considering the efficiency and easy availability of switchmode
supplies these days, I would never bother with a linear regulator
in a new design.
For instance national has a series of switch mode regulators (LM25xx)
which just requires a coil and a diode more than the usual LM78xx
If you are worried about noise from the swichmode, you can add more
filtering to the output.

Never attribute to malice what can adequately be explained by incompetence.
