Because I really like the model/UX of the staging area. I'm not worried about the tool being simple; I use it every day, so it's worth learning inside and out.

It's a much nicer experience IMO to be able to work on various different pieces, then iteratively run `git add -p` or similar to stage individual files or hunks, verify everything I'm adding with `git diff --cached`, then `git commit` when I'm actually ready and happy. It lets me fix multiple parts of my project at the same time, without interruption, while still letting me compose my batch of changes into multiple, self-contained changesets.

`hg record` feels really limited by comparison, and rushes you immediately into committing your selected changes, and then further makes it difficult to selectively amend more (partial) changes to that commit afterwards.
