I've been working on a GC-only app for several months now.  In practice,
I haven't run into major problems.

But I would say that the dev tools and docs are not quite 'GC ready'.
Lots of docs talk about autoreleasing and make no mention of GC.  The
(great) Debugging Magic technote has not a single hint for GC
debugging.  MallocDebug does not work with GC apps (you can still have
leaks in GC apps if your app also uses C/C++ code).  Rosetta does not
support GC code (could be nice for running unit tests).  OpenGL
Profiler.app does not work with GC apps.  Interface Bulider does not
support GC plugins.  Hopefully the tools with catch up soon.
