As you will see, your existing iPad is not compatible with Apple Pencil. This is not a marketing consideration, but is a technical limitation.

There are available third-party stylii that can be used with iPad - with mixed capability and usefulness. I’m certain that additional “help” with be forthcoming from other contributors soon - and some of it will be overwhelmingly lengthy in its content opinion.

You will find simple styli that are effectively a simple substitute for your fingertip. These may offer great precision in context of where you “touch” the screen of your iPad, but little else.

These have usefulness typically limited to so a subset of available App titles.
