Speaking of vector program alternatives, I was also told about iDraw by illustrator George Coghill (he’s been using it for a while now). iDraw seems quite feature-rich and offers both a desktop version ($25) and an iPad app ($9). Yes, $25 for a desktop vector program. Are you listening Adobe??
A clever product — a stylus for touchscreen devices designed to fit a Sharpie pen (and other brands) as a traditional pen lid. The Kickstarter funds have been fully pledged (though you can still contribute money), so the project is a reality.
