Apple faces some weaknesses that could threaten its future success. It relies heavily on Steve Jobs' visionary leadership, and questions remain about whether Apple can survive without him. Some of Apple's products still contain toxic chemicals, and its green policies have not gone far enough to satisfy consumers. Compatibility issues drive some users to illegally hack their iPods, undermining Apple's business model. Overall, Apple needs to strengthen its green credentials, plan for succession beyond Jobs, and improve compatibility to solidify its position in the long run.
