Until now, Logitech's Harmony line has been thename in programmable remotes. Now the company's back with three follow-up products, and they differ enough from earlier models to warrant an explanation. Instead of using a programmable IR remote, the Harmony Ultimate, Harmony Smart Control and Harmony Ultimate Hub each offload the IR-emitting duties to a networked device, allowing smartphones and tablets to act as remotes too. Additionally, the Hub uses Bluetooth to control your game console. Ranging in price from $99 to $349, the lineup covers almost every budget, with the Hub sold as a standalone accessory for smartphones and tablets. Meanwhile, the Smart Control includes a simple remote, and the high-end Ultimate Hub swaps a basic remote for the Harmony Touch. How exactly might these enhance your home theater enjoyment? Read on to find out.
