HTC Dream / T-Mobile G1 (2008)

The HTC Dream, as the first Android smartphone, launched the OS that now powers over 3 billion active devices. Its slide-out QWERTY keyboard and 3.2-inch touchscreen offered full Google integration from day one. Selling 1 million units in its first six months, it was 25% cheaper than the average iPhone at launch. While its hardware is outdated compared to #1, its role as the Android pioneer is unmatched.
