I'm a 3D artist and animator in the middle of updating my portfolio. If I won a new iPad, I'd purchase an Apple Pencil and use it on my character designs. Currently I use an old Wacom Intuos and would like to experience drawing directly on the screen. Try as I might, I can't match my drawing skills on paper with an Intros. I feel drawing directly on the screen will be the leap in technology I've been yearning for.
Currently I'm using Mischief for my sketching although I have experience of using Procreate. Procreate has a brilliant brush engine that I can only imagine shines with a pencil. I'm in an industry that shies away from Apple products (3D industry) and getting people to use the iPad with a stylus might turn some heads. Many are eager to get a Surface Pro 4 because it has a stylus/Photoshop/Zbrush. I on the other hand would like to try a product from what I'm hearing has a best-in-class pen/brush performance.
I have no interest in using he iPad for 3D production because of lack of industry quality software on iOS and no access to shortcut keys. The iPad would be entirely about painting and designing characters that I will be going on to modelling and animating. In short, I'm after something that will topple a Wacom Cintiq. Yes I know you can use Zbrush with a Cintiq and not on an iPad, but lord does the Cintiq have a terrible screen.
Also I am VERY interested in the palm rejection tech built into Apple products going into the future. This technology is probably going into other Apple products eventually and I am very eager too sample Apple's take on the whole area. When Apple enters a market, they tend to do it with grace. I also feel that reporting and demonstrating palm rejection has been lacklustre so far. Difficult to find an actual artist trying it out. I've seen the Disney views and even they refuse to rest their palm on the screen while drawing. So I'm eager to give the tyres a good kicking.
