Meet Pencil, a super cool pen for iPads. Very capable and reasonably priced. Unfortunately, needs an iPad 3 or better to use (we’ve got an iPad 2.)
I think direct stylus style input is neat, but truth be told, I’ve never been able to get into it. Back in my PC days, I had a nice Wacom tablet, and after the gee wiz period, it pretty much just went back into the box. I’m pretty sure I’ve still got it somewhere. Wonder if I could rig it up to use it with my MBP.
