Apple Acts in/for a Timely Matter

I was pleasantly surprised to have my latest iPhone offering, calendaRSS, smooth through the approval process. I submitted it on Monday and it was reviewed and approved on Friday, in stark contrast to the delays I previously experienced. Maybe it's because this is a "useful" app instead of being presented as a game? Now I have to work the weekend because I didn't have all the marketing materials ready! It's a wonderful, terrible problem to have.
