Welcome to the future. You may not be able to get a flying car, but you can now buy a lightbulb that you can program with your smartphone, that can change color at will, and that can last for five years. All for about $200 for a starter kit that includes 3 bulbs and the bridge that links them to your home WiFi network. Ars Technica calls Hue "awesome," and says that "Being able to control the color, brightness, and timing of your lights from your phone or computerâ€”and tying the lights together with your own on/off scheduleâ€”is addictive." Of course, you don't necessarily need a smartphone-controlled, color-changing LED lighting system. And as AllThingsD points out, this is "definitely a first version of a product" with some bugs and limitations. However, as Ars says, "if you have the spare cash, they are worth buying. They're just too fun and too addictive to not own."
