Logitech took advantage of the opening of CeBIT to add a spate of accessories to its lineup. The Harmony 650 and its monochrome sibling, the 600, provide a newer mainstream jumping-in point for universal remotes. While they don't have the touchscreen of the Harmony One, they now have one-button presets for common tasks like watching a movie or playing music that will handle all the associated steps at once. Their displays still provide a visual guide for less automated functions or for picking a favorite TV channel by its logo.
