Interesting article but a little misleading at the start. That first example (billing management software) touts 900 paid users @ $65 per month after moving away from the freemium model, but how many of those 900 users would have never become users at all if the software was not initially free? It's much easier to start charging a customer once they are locked in and familiar with the software. Maybe a "first year is on us then it's paid" model is a good compromise between freemium and paid software, with the option to upgrade sooner if you want support and/or some advanced features.
