It's an interesting article and I love how they're approaching app sales. There are some successes out there that are doing well with this sales model (the most recent download I've had like this is Outwitters: http://onemanleft.com/). It is hard to see where the app sales ecosystem is going though (and if consumers will really dictate this path).

Weird, Outwitters is listed as free on the one man left website, but iTunes has it as $0.99
