Why do you want to make my job more difficult by requiring me to carry a sketchbook on me at all times? Why do you hate trees and the environment when we have a perfectly good moleskine in our pockets at all times called the iPhone? I seriously don't get what's wrong with you people who hope that great features never come to the iPhone because a guy who has been dead for five years didn't like crappy stylus back in the day and now we've got this amazing Apple Pencil that works really well for us artists and designers. Get over Steve's death and stop trying to trample on progress. The Pencil is incredible technology and implementing it in the iPhone would be simple. It's not going to change the primary input method in the slightest because most people aren't going to pony up for a $99 accessory and it has more of a singular purpose, which is for drawing. Why do you get so mad when you see someone using something in a way that doesn't jive with your expectation? Maybe that works better for that person because they have some sort of disability? Did you stop to consider that? I do UX/UI Design in apps and the web for a living, and I'm constantly surprised with what our users tell us in testing, especially as it relates to accessibility testing. There are certain things that help them accomplish tasks easier. They could have shaky hands from parkinsons and maybe they can more easily tap things with the Pencil. You don't know, so don't judge.
I am not against the Apple Pencil per se, not at all. I just don't think it should/would well pair with an iPhone. But then again, I don't think the iPhone is a good device for scribbling, imho it's way too small, even the plus (not a big fan of the plus either, though).
What's wrong with the iPad Mini for all those tasks? I really do hope the pencil comes to the mini, eventually.
And yes, I am in favor of using things the way they are intended to. You wouldn't start carrying your car and take the bus with the car either, would you?
