1. What a huge saving — 0,002¢ per repo copy. Don't spend it all in one place.
2. Bookmarks is core feature since March 2011. This basically means those who pushed "move to Git" decision, haven't checked if anything was updated in Mercurial (and with bookmarks in particular) since then at least. This is pretty understandable — it is known that only software gets updated is one you're paying attention to, others don't.
3. As ezquerra mentioned, those extensions Mike is probably referring to, are shipped with Mercurial, and are enabled with only single line added to .hgrc. Not mentioning those extensions do not _emulate_ Git features, they _reproduce_ it.
