The Anatomy of an Epic App Store Sale: 1.1M downloads in 1 WEEK

http://www.slideshare.net/pinchmedia/iphone-appstore-secrets...

A couple of observations:

  - price elasticity, the non-linear relationship
    between price and consumption is something anybody
    that sells products on-line should study

  - that's not the same as the difference between free and 
    paid, for people to pay for something you have to cross
    a barrier, and even $0.99 is a barrier strong enough
    to stop a large number of people to download your app

  - this article is from May, I'd be interested to see how
    it turned out in the longer term and what the total take
    on this app was versus what it cost to develop it

  - even the most trivial stuff can make you money if you 
    market it right

  - timing is everything
