A few months after the arrival of the iPhone 3G, HTC launched the first smartphone with Android, Google’s operating system that is now the most widely used in the world. With its design reminiscent of PDAs (Personal Digital Assistants), a 3.2-inch touchscreen and slide-out that revealed a physical QWERTY keyboard and trackball, the HTC Dream has the honor of being the first to have incorporated it. Despite its initial success, it was soon forgotten by the immediate proliferation of Android options that largely dispensed with physical keyboards.
