>> I am John Falcone, Executive Editor for CNET.com and this is the Logitech Harmony 600. This is one of Logitech's most affordable Harmony universal remotes to date retailing for just $80. Like nearly all Harmony remotes this one is programmable via Windows PCs and Macs using Logitech's web-based software. It controls up to five devices and uses simple task-based commands such as Watch TV, Watch a Movie or Listen to Music. Overall, we really like the look and the ergonomics of this remote. That is not a surprise because it is the same basic design as the more expensive Harmony 650 and 700 models. In fact, the only real difference between the Harmony 600 and the 650 is the 600's LCD screen in monochrome instead of color, so we can't use the colorful logos for favorite channels. The LCD screen is surrounded by five contextual buttons and you can page through to additional screens to multiply the available options. Otherwise, the Harmony 600 has all the buttons you need for controlling a TV, cable box, DVR and DVD or Blu-ray player just to name a few of the possibilities. To program the Harmony 600, you connect it to a PC or Mac using the supplied USB cable and fire up Logitech's web-based software. Once you identify the make and model number of your devices, the system automatically downloads the correct codes from Logitech's massive database which includes more than 200,000 devices. Then you answer a series of questions about how they are connected to one another, in what were they should be powered up and how they fit in to each task. The software handles most of the heavy lifting and you can customize and troubleshoot as needed. It may be a bit challenging for newbies, but it is still easier than multi-step macro programming you need to do for many other universal remotes. Once we set it up we found that the Harmony 600 controlled all of the IR-based products in our home theater system reliably and without any hassle. If you really need the color screen, you can pay an extra 20 or so dollars to step up to the Harmony 650. Otherwise, the Logitech Harmony 600 is a great option for replacing up to five remotes in your home theater. I am John Falcone for CNET.com and this is the Logitech Harmony 600.
