A brief history of USB, what it replaced, and what has failed to replace it

USB really came of age with USB 2.0, and USB 3.0’s increase in speeds to 5Gbps […] it takes less time to perform system backups or to move giant video files around, and it relieves a bottleneck for 802.11ac or gigabit Ethernet adapters. It’s relatively comfortable to run entire operating systems from USB 3.0 hard drives or flash drives, especially useful if you’re trying to troubleshoot a machine or recover data from it. USB ports are often the only ports available on laptops, especially since Wi-Fi has reduced the need for dedicated Ethernet ports. The ubiquity of the interface guarantees support from all major chipmakers, from Intel to Qualcomm to AMD. – Andrew Cunningham,Ars Technica
