I had my eye on Pythonista for a while, and finally purchased it last week when it updated to version 1.2. My only regret is that I didn't purchase it earlier. I've had so much fun writing scripts and automating tasks on my iPhone and iPad. I uploaded a few of my own to GitHub for safekeeping, so feel free to check them out and take some ideas.
