Cherry picking. Darcs' cherry picking abilities are fantastic, while every
other system (and I've tried most of 'em by now) seems to have at least one
big inhibitor to cherry picking. For the way I work on the systems I work
on, good cherry picking is a must.

I've seen instructions in projects' development guides to avoid merging when
it's not absolutely necessary to avoid polluting the change history with
merges. A revision control system that makes its users avoid merges seems a
bit suboptimal to me.
Some people are like slinkies. They are fun and don't actually serve any
real purpose, but they still make you smile when you push them down the
