Here's what it looks like after I sanded the first coat:
You can see how even at this point a little sanding is a good thing. You're not going to make up for a lack of prep work on the spackle, primer, or first coat, but if you sand after every coat you will have a nice finish.
Here's another little tidbit:
At the very least, hitting the paint lightly with some sanding screen will knock off all the little snots you get if something gets in the paint. Now, you shouldn't have a lot (if you see a lot of little white specks, you need to reevaluate your painting technique), but it will take care of the errant little snot. This is from when the roller hit the smoke alarm wire, the wire hit the ceiling, and must have left a chunk of spackle.
For most situations I guess you don't have to go crazy. High end painters will sand like this. Average painters just put on coat after coat.
The litmus test is when you turn on your cove light.
