Apple Products Evolution

Microsoft continued to gain market share with Windows, focusing on delivering software to cheap commodity personal computers while Apple was delivering a richly engineered, but expensive, experience. Apple relied on high profit margins and never developed a clear response. Instead they sued Microsoft for using a graphical user interface similar to the Apple Lisa in Apple Computer, Inc. v. Microsoft Corporation. The lawsuit dragged on for years before it was finally dismissed. At the same time, a series of major product flops and missed deadlines sullied Apple's reputation, and Sculley was replaced by Michael Spindler.
• 1994–1997: Attempts at reinvention
By the early 1990s, Apple was developing alternative platforms to the Macintosh, such as the A/UX. Apple had also begun to experiment in providing a Mac-only online portal which they called eWorld, developed in collaboration with America Online and designed as a Mac-friendly alternative to other online services such as CompuServe. The Macintosh platform was itself becoming outdated because it was not built for multitasking, and several important software routines were programmed directly into the hardware. In addition, Apple was facing competition from OS/2 and UNIX vendors like Sun Microsystems. The Macintosh would need to be replaced by a new platform, or reworked to run on more powerful hardware.
In 1994, Apple allied with IBM and Motorola in the AIM alliance. The goal was to create a new computing platform (the PowerPC Reference Platform), which would use IBM and Motorola hardware coupled with Apple's software. The AIM alliance hoped that PReP's performance and Apple's software would leave the PC far behind, thus countering Microsoft. The same year, Apple introduced the Power Macintosh, the first of many Apple computers to use IBM's PowerPC processor.
