Steve Wozniak is who built the original Apple, the hardware and the software, Steve Jobs did manage to create the Apple image and sell himself as some kind of a tech guru in the process.
Apple's worst years were when Jobs was gone and the company's management was trying to beat IBM clones when Apple had few distinguishing features and the clones were competing on thin margins, while Apple largely tried to avoid the (except the few years when they allowed Apple clones). When Jobs returned, the OS changed, the CPU architecture changed, the shape and design of the computers changed, and new computing devices (iPod, iPhone, iPad) and created the iTunes + App Store.
