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 II series
The Apple II series (trademarked with square brackets as "Apple ][" and rendered on later models as "Apple //") is a family of home computers, one of the first highly successful mass-produced microcomputer products, designed primarily by Steve Wozniak, manufactured by Apple Computer (now Apple Inc.), and launched in 1977 with the original Apple II. In terms of ease of use, features, and expandability, the Apple II was a major advancement over its predecessor, the Apple I, a limited-production bare circuit board computer for electronics hobbyists. Through 1988, a number of models were introduced, with the most popular, the Apple IIe, remaining changed relatively little into the 1990s. A 16-bit model with much more advanced graphics and sound, the Apple II, was added in 1986. While compatible with earlier Apple II systems, the II was in closer competition with the Atari ST and Amiga.
