When Freemium's Good, It's Very Good and When It's Bad, It's Horrid

When I read a new report on app store trends for 2013 recently, my most irritating fear was confirmed: The "freemium" app business model has not only won the app sales model, it has handily crushed the paid app model -- squeezed it down into a tiny sliver of relative revenue. The results are so tilted toward free apps with in-app purchases as a business model, in fact, that even more new apps will apparently be written entirely with the freemium model in mind. That's why I'm sitting under my desk and rocking back and forth as I type this sentence.
