Siri
Siri was originally released as a stand-alone application for the iOS operating system in February 2010, and at the time, the developers were also intending to release Siri for Android and BlackBerry devices. Two months later, Apple acquired Siri. On October 4, 2011, Apple introduced the iPhone 4S with a beta version of Siri. After the announcement, Apple removed the existing standalone Siri app from App Store. "TechCrunch" wrote that, despite the Siri app's support for iPhone 4, its removal from App Store might also have had a financial aspect for the company, in providing an incentive for customers to upgrade devices. Third-party developer Steven Troughton-Smith, however, managed to port Siri to iPhone 4, though without being able to communicate with Apple's servers. A few days later, Troughton-Smith, working with an anonymous person nicknamed "Chpwn", managed to fully hack Siri, enabling its full functionalities on iPhone 4 and iPod Touch devices. Additionally, developers were also able to successfully create and distribute legal ports of Siri to any device capable of running iOS 5, though a proxy server was required for Apple server interaction.
Over the years, Apple has expanded the line of officially supported products, including newer iPhone models, as well as iPad support in June 2012, iPod Touch support in September 2012, Apple TV support, and the stand-alone Siri Remote, in September 2015, Mac and AirPods support in September 2016, and HomePod support in February 2018.
Apple Pro Mouse
The Apple Mouse (formerly Apple Pro Mouse) was introduced in July 2000 at the Macworld Conference & Expo in New York City. Apple Computer was one of the first companies to ship an optical mouse as the standard input device. While the industrial design of the Pro Mouse was handled entirely by Apple's in-house designers, some of the hardware has been engineered by Sparkfactor Design. The Pro Mouse was included with the Power Mac G4 Cube, also introduced at that year's Macworld. Apple was the first company to use USB mice and keyboards exclusively when they introduced the "hockey-puck" mouse with the original iMac G3 in May 1998. Like the "hockey-puck" mouse and all future mice Apple would make, the Apple Pro Mouse was a USB mouse with a much shorter cord than its ADB predecessors, its 2-foot cord was designed to plug neatly into one of the two ports of the Apple Pro Keyboard's built-in USB hub. The Apple Pro Mouse also featured a unique mechanism to allow for 3 click force settings for the required pressure to click the mouse. The Apple Pro Mouse was originally released on the iMac G3 "Snow."
