I was curious about this myself, I have used AR for years now and I was
interested in DM's promise of no migrations and optional lazy loading of
fields. I have no problem expressing my fields in the models (I
actually like it) and I have no problem being committed to MySQL. If DM
can update your schema automagically when seeing an
incompatibility/update with your model then I won't sleep for a week due
to the magic of it all.

I used to think that migrations were the best thing since sliced bread
but due to the fact that AR attempts to cater to every major vendor, I
usually have to go in a hand tune my migrations anyways (bigint and
foreign key constraints which I realize many feel are unnecessary when
working with RoR). I also used to follow OG as well but after some
playing around, i came to the conclusion that updating the schema with
it was far more difficult than it was with AR.

Merb right now is a big carrot for me and it has direct support (through
gem dloads) for haml AND DataMapper so I think something truly great (or
at least very exciting) is in the mix! Due to the fact that I am a
coward however, I still use AR at work as I am very comfortable with it
and I finally got used to a lot of it's black magic through
method_missing craziness.

Merb/DataMapper is a cinch to dload and set up so you should see it for
yourself..
