In my scheduling app I need to be able to let the user specify the

I have done a little testing with a CalendarDay class that has a
BOOL iVar for each hour of the day (I just need hour resolution
and 2 choices--working or not working for each hour). I got to
hour 3 and realized there must be a better way, although this way
of doing it did work just fine with my Bindings test, using an
NSMatrix of NSButtonCell checkboxes.
But so many accessor methods to fully implement it! (48)
Bindings haven't obsoleted data-source methods for every purpose.
In your situation, I wouldn't use bindings.
Before completely tossing out bindings, I would first look into if a
custom binding may be worth it. I have written custom bindings for
matrix subclasses and they've been very useful. For example, I have
a 'multiplication table' switch group (single control; one cell per
table). It has a single 'selectedTables' binding.
Note that I'm not saying to always use bindings. In some cases, the
amount of code and/or complexity to set things up may be more than a
non-bindings solution.
