It hasn't been a legitimate name in computing for over 20 years, but somehow the Commodore brand always manages to find a way back into our lives. In 2004, it came back as a simple TV-Game joystick. In 2011, Commodore USA sold gaming PCs stuffed into retro-styled keyboard chassis. Today, the brand is back again--as a nostalgia-stamped 5.5-inch Android smartphone.
