I'm interested in understanding how many mobile designers sketch on an iPad as opposed to paper and why...
The slight lag I experience when sketching on the ipad is a deal killer for me. As the technology gets better, however, I definitely see myself switching over.
I'm not as sure as you are about switching over, but I am with you on the (ever so slight) lag, and would like to add "the millimeter between your finger and the screen". They together create a disconnect that I'm not comfortable with.
That said, I love doing digital art on my Wacom. Just not sketching. It's just not as fast/precise/easy.
I'm using paper and pen/pencil, shoot a photo with my iphone and send to myself or to the person that I need to show it. I think it's faster and I like to draw on paper!
I do. I prefer use Adobe Ideas rather than Paper by 53. I like it because it's vector, I can zoom the whole screen (not just a small area like in Paper), once the sketch is saved I already have access to it in my Creative Cloud drive (it's works even without a subscription), and while the Paper interface is slick the Ideas UI is a lot easier to use.
So definitely check out Adobe Ideas!
I recently started doodling (and I mean doodling) on the iPad in Paper by FiftyThree for random ideas, even before the sketching phase. I save real sketching for actual paper, mostly because it feels better, I can write tiny margin notes and I make less mistakes I have to "undo". I can imagine if I got better at controlling how I draw on the iPad (which seems to be a new skill set in itself), I would potentially do much more sketching in there.
PS - I started using a cheap iPad stylus lately and its improved my enjoyment and precision a LOT (http://www.amazon.com/3M-Touchscreen-ST1GY002369-Stylus-Packaging/dp/B0054R1EY0)
I mindlessly doodle for fun using Paper (the app), often while I'm working on other things. It's calming, frees up my computer for other work, and doesn't require me to keep switching between tools for color (as compared to sketching with physical paper).
That said, I greatly prefer sketching on physical paper while thinking through ideas, and a wacom when doing illustration-y work.
I do both pen and paper and iPad. I tend to use Paper/Procreate on iPad when I am its easier for me to use the iPad and for some quick sketches since its easier to send those. For something that needs to be more refined, I will use pen and paper for those.
i prefer actual paper, i find the ipad screen too small for sketching
I've been sketching on paper, I'm eager to try Paper by FiftyThree ever since they launch Pencil.
I wouldn't say that I solely sketch on my iPad compared to pen + paper, but it's a practice that has definitely been growing as the Paper app from 53 has gotten better. Pen and paper is still usually the first thing I grab, but more and more I find myself using the iPad for more.
I love how it creates a permanent digital file, rather than a piece of paper I need to hold on to for later archiving needs.
Very easy now to send team mates sketches via email, especially when they are working from home as opposed to scanning sketches.
If I am designing an iPad app, my sketches are already the correct size.
