Bug Report Problem Report Title: User cries because the iPhone won't accept media from more than 1 computer. Product: iPhone Version/Build Number: 3.1.2 + later Classification: Enhancement Is It Reproducable? Always Problem Details: Please use the description format required by Apple Engineering. Summary: Loyal Apple customer and computer literate user reduced to tears because iTunes refuses to let her copy non-DRM content from multiple source computers onto her iPhone. "I hate Apple!" she cries as she storms out of the house, her $500 telephone flung to the ground in a fit of rage. Steps to Reproduce: Buy two Apple computers, padding Apple's accounts. Keep non-DRM music and videos on these computers. Buy one Apple iPhone, further padding Apple's accounts. Expect to use it as an iPod. Sync the iPhone with the computer #1. Copy some non-DRM music onto the iPhone using iTunes-supported methods. Additionally copy some authorized DRM content onto the phone, in order to ensure we are compensating content holders. Plug the iPhone into computer #2. Now attempt to sync non-DRM music from the computer #2. For good measure, attempt to copy some authorized DRM content as well. This ensures that the loyal user has paid money for the transaction, raising the stakes. Expected Results: User finds that it is possible to use the 16 GB disk on her phone to store her personal music collection, no matter where it came from. User praises iTunes' ease of use as she buys more DRM content from the iTunes Store. User buys more Apple hardware, and tells her friends to do the same. Actual Results: iTunes refuses to copy files from both computers. It offers he the option of wiping the content on her phone in order to add content from computer #2. If at first the user thinks she has succeeded, she soon realizes that her content from computer #1 has been erased, only to be replaced by the selected content from computer #2. Enraged and in tears, user screams, "I hate Apple!" and throws her very expensive telephone on the ground. User realizes that she has been had. All that extra storage she paid for is practically inaccessible under many scenarios. User refuses to buy more Apple hardware, and user will never pay for DRM content through the iTunes store again. Notes: The iPhone is sufficiently powerful that the user considers it a computer. Just as she can copy arbitrary content into the iTunes libraries on computer #1 and computer #2, she expects to copy arbitrary content onto her iPhone. Instead, she is shackled by a "synchronization" paradigm that arguably works for contacts and notes but is entirely irrelevant to a 16 GB mobile library of music and videos. Please don't make your loyal users cry.
