PCB designers / engineers: Hey, hardware people - parallel buses are a pain.
Serial is easier to handle. Can you do that?
IEEE-1284 and RS-232: Okay, here's USB!
IDE/ATA: We can do that! SATA.
SCSI: Cool. Here's SAS.
PCI: ... how about a really fast serial connection, but we have a bunch of them side-by-side?
