As of my last knowledge update in September 2021, the iPhone 15 had not been released. Therefore, I can't provide specific information about its worth or features. However, Apple's iPhone models generally offer high-quality build, advanced features, and a robust ecosystem. When considering a purchase, it's important to assess your individual needs and budget to determine if a specific model is worth buying. Keep an eye on the latest reviews and connections game comparisons to make an informed decision.
