Return Of The T-Mobile Sidekick

Before the iPhone and Android existed, T-Mobile sold a phone called the Sidekick, which was developed by a company called Danger. All Sidekicks had hardware keyboards in a landscape orientation, with the screen sliding or popping out to reveal the keyboard. The Sidekick software was optimized to work with servers on the Internet to store photos and music, requiring the phones to have a constant connection to the Internet.
