I made myself a stylus or Sketchbook Pro out of a roll of anti-staic film jammed into a biro but its not as responsive as I would have hoped.. I plan to pick up a proper stylus in the next week or so. The multiple use aspect of the iPad is what is most appealing to me I think - the combination of video editing, drawing and photo editing along with books, comic books (guilty pleasure) and navigation with an external GPS unit has pushed me to use my iPad for all my travel computing (unless a larger job requires a laptop Final Cut editing suite) I will try and post some of my conceptual storyboards and sketches in the next few weeks..
Meantime here is a quick one I knocked out on a saturday afternoon - finger and home-made stylus. I created this to prove a point to a friend of mine - a fellow illustrator - who was torn between picking up an iPad 2 and Sketchbook Pro or going full whack with a Macbook Pro, Photoshop and a Wacom. His criteria was to have a light portable solution for polishing up his pencil and ink sketches in the computer. For professional, highly polished output - the Macbook Pro / Wacom route is the way to go, I'm still keen to use the iPad for on the road work or rapid prototyping with a client in the room - I would be less keen to use it for final print work.. I love my Wacom tablet and I use it literally every day even in my corporate job.
As it happens my friend won a Macbook Air in a company competition so he's going to try and cram Photoshop on it to use with a Wacom tablet - I will be intrigued to see how he gets on..
