Apple’s iTunes app is so complicated you need a guide to figure it out. Rene Richie has it:
The iTunes Store app is your one-stop media shop on every iPhone, iPod touch, and iPad. With it, you can buy any song or album in Apple’s catalog, rent or purchase movies new and old, get episodes or season passes for your favorite TV shows, download ringtones, and more. It’s built right in, it works with Apple’s Videos and Music apps, and it syncs with Apple TV and iTunes on the Mac or Windows PC.
It’s a love fest list of topics for an Apple app that increasingly is more difficult to love.
