I'm still in data-gathering and thinking mode, but meanwhile I recommend the videos on Apple.com.
The iPhone 6s+ is good, 12MP camera!
And finally it came: the iPad Pro! Ten wild supermodels could not keep be away from this beauty.
Not the least: it has Apple's own pressure- and tilt-sensitive stylus, called Apple Pencil. This is a huuuuuge boon for artists who can't pay the big fees Wacom's screen/tablets demand.
This amazing device is a very big step for tablets as creation devices. But also as reading devices for text books, technical books, Comic book, illustrated book, art books, etc.
