Not to mention that the ONLY way to get an application into an iDevice is via 
the Apple store.  (At least if you don't expect end users to "jail-break" their 
devices to allow downloads from "unauthorized" sources.)  You can't just put 
your app out for downloading on a site like SourceForge, TAPR.org, a Linux 
repository or your own website.

Even if you want to give the application away for FREE to end users, it costs 
the developer thousands of dollars in charges for specialized development 
tools, yearly charges for access to the Apple Store, etc.  And that's after you 
pay to submit the app to Apple for approval before it goes live in the store, 
with no certainty that it will be approved.

Charges like these are not too significant for mainstream consumer or business 
apps that will sell a significant number of copies, but are a MAJOR obstacle to 
low-budget part-time hobbyist-type developers in a niche field like APRS.
