This has been my experience, too.

You may want the following options in the convert command (which make it
run pretty slow, but the result is worth the wait):
convert -density 288 -crop 0x0 nice_pic.ps nice_pic.png
The meaning of these two options is explained clearly in the man page.
Basically, the density spec increases the resolution (higher quality)
while the crop spec chops all but two pixels worth of the background
from around your image. You may need to re-size this png after importing
into PowerPoint or some such program.
