Logitech has added two more Harmony remote controls with the unveiling of the Logitech Harmony 600 and Logitech Harmony 650. The only difference between the two is that the Harmony 600 renders commands for the required devices in black and white while the Harmony 650 does it in color.

Both remotes can replace up to 5 different models. The Logitech Harmony 600 retails for $79.99 while the Logitech Harmony 650 will cost about $99.99. They are expected to hit stores this month.
