16. HTC Hero
Key features: 3.2 TFT capacitive touchscreen, 528 MHz ARM 11 processor, Android 1.5 OS, 3G/wi-fi, and 5MP camera
Complex says: Its customizable interface is pretty in-depth as users can configure themes to appear on any of the seven homescreens during specific days of the week. A Twitter and e-mail widget is also pre-installed, allowing you to stream live tweets and browse emails simultaneously. The Android-powered device also offers an Eclair OS (2.1) upgrade, giving the Hero a more modern-day feel.
