Apple, Intel and the ports business
What Intel has and Apple lacks on its own is the ability to garner widespread adoption of new cabling schemes and the economies of scale that follow. Back in the 80s, Apple largely just ignored the generic PC world and its third-rate port specifications. While PCs shipped with RS-232 serial ports and Centronics parallel ports for printing and slow disk drives, Apple gave its Macs an improved RS-422 serial port that was backwardly compatible but offered the ability to accommodate AppleTalk/LocalTalk networking.
On the other hand, Apple also adopted the high performance SCSI interface for hard drives and printers and scanners, something that was deemed too luxuriously expensive for mainstream PCs. That subsequently kept SCSI and its interface support chips relatively expensive to manufacture.
Steve Wozniak's Apple Desktop Bus was adopted by Apple in 1986 for connecting together a variety of input devices and serial peripherals, from keyboards and mice to stylus tablets, barcode scanners and video cameras. Despite some use outside Apple by Sun and NeXT, ADB similarly never caught on among generic PCs, which continued using two PS/2 connectors, one for the keyboard and one for the mouse. That similarly helped keep ADB peripherals relatively expensive.
Apple then developed FireWire as a high speed cabling system that could accommodate the future needs of digital video and replace SCSI with simpler cabling. This too was slow to broadly catch on among PC makers. Intel delivered its own USB specification as a slow, ADB-like peripheral connection standard to replace RS-232 serial, Centronics parallel, and PS/2 connectors on PCs. While it didn't initially gain much attention among PC users, Apple adopted USB as a way to jettison both ADB and serial ports on the iMac, and kickstarted the market for low speed USB peripherals.
Intel then upgraded the USB standard to 2.0, a move that encroached upon the performance of FireWire (without actually delivering many of the features FireWire was designed to provide). This effectively killed any mainstream market for FireWire outside of niche markets, and again subsequently kept FireWire relatively expensive to implement.
Stronger together
On their own, Apple and Intel had limited success in promoting new standards into the mainstream; together, the pair seemed to be very complimentary partners. Intel acts as the establishment insider, holding down prices with high volume mainstream production,
while Apple serves as the vanguard, pushing new technologies into an industry notoriously resistant to change."
