I am more inclined to think the customers may be right and this app is not worth $50 to them. There are competing free products, but also competing work flows like using Dropbox to move documents between your two laptops depending why you are using two. The guy has clearly thought about this a fair amount.

There is apparent oversupply of app developers who seem to think they will make money but the evidence is very few will build sustainable businesses while the rest just help Apple out by adding diversity.
