The iPad Pro and the app Procreate is a powerful combination. An update to Procreate in Jan. 2017 allows you to import Photoshop files with the layer structure (including grouped layers) intact. Procreate allows you do a screen video capture of your illustration which was used to export this video.

The iPad Pro, for illustrators, is a revelation. The wide gamut screen is as good or even better than any desktop monitor. The Apple pencil is as sensitive as a Wacom stylus but without the weight and size. The battery life of the pencil is surprisingly good.
