Apple’s new adapter is only intended to connect a first-generation Apple Pencil to the new iPad, it can’t be used to let the older Pencil work with iPad Pro models designed to have the second-generation one.
This means that in theory, an existing first-gen Apple Pencil owner could skip paying $129 for the second-generation Apple Pencil. Or even a brand-new user with a USB-C iPad Pro could save $30 by buying the first-gen Pencil with its now-bundled adapter.
USB-C iPad Pro models are designed to work with the second generation Apple Pencil, and they will not recognize the new adapter when it’s plugged in. Monday’s reviewers tried, to no avail.
