So how to decide? Given that WunderRadio is $6 and Radioshift Touch is $10, anyone with $20 in their pocket can buy both (and spend the remaining four bucks on two TV episodes at the iTunes Store) and have both quantity and quality. If you're strapped, though, the deciding factor is likely to be whether the stations you care about are supported by one application or the other. To see which stations Radioshift Touch can access, visit Rogue Amoeba's Online Station Browser. Enter a keyword or zip code to search for programming that matters to you. Weather Underground offers a similar service for seeking stations and programs.
