I wonder what the pencil means for Wacom? It looks fantastic, and from my naive perspective looks like it'd be just as capable as a high end Wacom tablet. Any artists here who can chime in?
I haven't tried iPad Pro nor Microsoft Surface, but Wacom has a texture on the surface which makes a lot of difference when drawing and painting. Even Cintiq has a layer of that on it. Even if they've solved 'drawing on glass' (which should be shit compared to textured surface), there's still that whole issue of proper apps to draw in compared to iOS.
In my studio with 12 or so creatives, none have shown any interest in trading out their Cintiqs for an iPad Pro + Pencil + Duet (or some other screen sharing app), despite having a few around the office and many of them having played around with them. That said, I could see many artists that don't like to tether themselves to an office liking the iPad Pro very much.
I tend to forget one at home and one at the office. So I keep one in my briefcase just to be sure. I accumulated the other 2 over months. Trust me, spending $100 on a writing utensil pains me a little, but not so much it precludes doing what it takes to get the work done.
You could have lied and said you actually use two at once. I had a professor that could do that with chalk once. (His lectures were to information what costco is to groceries.)
On the Surface side, there's Gabe from Penny Arcade, who's kind of informally become their artist advocate. If the Pencil's fidelity is as good as the Surface's -- and I wouldn't expect it not to be -- it seems like it would be perfectly capable.
That said, the Surface also works because it can run full versions of programs like Photoshop. I don't know how that plays out on iOS.
