That's normal, given that you are a longtime CakePHP user, hopefully it
will make sense to you very fast :)

If you have been using CakePHP for some time, then I guess you don;t need
models to be explained to you. But in plain english, it is where the core
of your application exists, when any user interaction is taken away. That
is, all data processing, updating and the rules to follow to keep your data
sane.

Both ways are exactly the same, we offered the 2 alternatives to make users
coming form 2.x feel more at home. I would say the first form is preferred
as it is more flexible.

I don't think it is, on the contrary, I feel that the ORM is much more
approachable and understandable that its previous incarnations.

I would like to know what is exactly confusing you, so we can help you
understand how things work. Let me also suggest buying tickets for
cakefest, much of the ORM internals, tips and tricks will be explained in
detail there :)
