Cables are disappearing. Communication between components, such as pointing devices, microphones, displays, printers, and the occasional keyboard uses short-distance wireless technology.
Grader A: partial
Short-range wireless (Bluetooth, RF mice and keyboards, Wi-Fi printers) was common in 2009, and Bluetooth headsets were mainstream for phones. But most desktop peripherals, displays and printers still connected by cable in 2009; cables were not disappearing.
Test: At least 50% of new peripheral units wireless: met for phone headsets connectivity in phones, not met for displays, printers or most mice and keyboards in 2009. A measurable share above 5% exists.
Grader B: partial
By 2009 Bluetooth headsets and wireless mice/keyboards were common and Wi-Fi printers were appearing, but displays, most printers and most desk peripherals still used cables.
Test: Share test: wireless peripherals (headsets, mice) well above 5% of users; cable-free component links not the norm by 2011.
