Sure enough, just last Friday, I waltzed into an Apple Store at 9PM and bought one.
The first thing I found myself doing with it is scribbling in Notes.app. Ten minutes later, I downloaded Pigment and the rest is history.
Really, it's not history, but I'm having a blast and am considering opening a section on my site for some of the work I've done. Pigment lets users export in glorious detail (up to 4096px in either direction) so long as they've paid. At $10/month (or $5/month paid yearly), it's not an inexpensive app, but the flow of designs is strong and the current collection is pretty large.
I've found myself spending several hours at a time just plugging (tapping and stroking?) away at the app and already have a couple pretty cool pieces to show for it.
