See Apple and Red, Yellow, and Blue boxes.
It is well known that 1990s Apple struggled to differentiate Macs vs. cheap beige PCs running Windows 3.1 and Windows 95 that could run the same user programs (Office, etc.) And that Mac clones cannibalized Apple's dwindling market share.
Jobs killed off clones, and solved the differentiation problem with the iMac in 1998 and Mac OS X in 2001; subsequently the iPod and iPhone focused on device categories where Windows was not dominant, and the iPad beat Microsoft at its own tablet PC game.
This is a nice collection with terrific documentation of Apple's "vintage" history from the 1970s to the 1990s. For example you can compare Macworld/MacUser vs. PC World magazines at the same time to see both sides of the Mac vs. PC war/friendship, and history of the computing industry in BYTE.
