What do you think of the Freemium model? Most websites providing e-services provide a freemium model to entice visitors to become members and then upgrade for additional services.

Even a few years ago, most e-services were pay or no service. Now, consumers expect a free service. What do you think?

I am planning an online business and a freemium model seems to be the most popular and viable in today's business world. Have you used a Freemium model on your business?

As I have perused through the free iPhone apps, I noticed many apps are offered free and then one has the option to upgrade to a paid version. Similar to the freemium version. What do you think of this?
