BlackBerry 6210 (2003)

The BlackBerry 6210 (2003) was the first device to integrate a full mobile phone with push email in a single handheld unit, revolutionizing business communication. It pioneered the always-connected paradigm with its trademark QWERTY keyboard and secure BES server integration, and its enterprise focus helped BlackBerry dominate the market, peaking at 80 million subscribers by 2012. While the Nokia 3310 focused on durability and fun, the BlackBerry 6210 is credited with creating the productivity smartphone category, a benchmark that later devices like the Google Pixel would build upon.
