Procreate and iPad Pro.... is it worth it?

The iPad is pretty versatile and can definitely be a worthy investment. The basic iPad + Apple Pencil is good as a basic drawing tablet or second monitor. The iPad Pro + the new Apple Pencil are quite a bit more expensive, but you get a nicer display, better drawing response and a pen that wirelessly charges.

And Procreate is definitely a good option as far as drawing apps go.

I'd say go with a new iPad, it's a very fun tool IMO, and app availability is constantly growing.
