To be fair, yes, the Droid will not be a harden 100% Corporate phone, although given how it was designed, its general aim is not 100% Corporate. The iPhone incorporated the Corporate side as an after thought as well, but given the nature of Apple, it has a much stronger basis to try and do majority corporate level work.
When you look also at the fact that Google's Sync doesn't seem to do much for Outlook as far as beyond the Calendar Sync, I believe the mainstay focus hasn't been on Exchange or MS Exchange level focus, so there isn't as high of a level.
Apple has it because they are shooting for Corporate and Home use, although some of their Mac in MSAD environment documentation is highly lack luster from what I have tried, the fact is that most of it is there for their focus.
Google will probably need a push from people about more interoperability to put more into it, and that is where the users are important to pass this information along.
