Adobe Illustrator. Which is probably a teetering pile of kludges on top of hacks on top of "quick fixes". But I've been using it to draw for about fifteen years now, I have a sixth sense that tells me I'm about to do something that may cause a crash and makes me hit "save". Earlier this month I was playing with running it on a Surface, and ultimately stopped because there is some interaction between Illustrator and the drivers for the stylus MS used in that device that drops the first half-second of every pen stroke I make. And I draw fast. So one of the things beneath it that's so reliable I never even consider it could be a problem is the tablet drivers I'm used to using with a Wacom tablet on my Mac. (There was a lot of other yak-shaving in those weeks, in which I tried to turn a Windows system into something that wouldn't drive my Mac-using self crazy, and into a super-portable art tool. Keyboard remappers, Dropbox, tons of Windows settings... the only part that wasn't pretty unpleasant and tedious to wrangle was Dropbox.)
