With consumer electronics changing so quickly, it's hard to know when is the best time to buy. Should you wait for that new TV you've been wanting, since a new model is about to be released? A new website, Decide.com, will tell you to "Wait" or "Buy" based on when a new model is expected to be released. Decide bases the recommendation on past model releases, news reports, and the like. Decide was founded by two executives from Farecast, Oren Etzioni and Mike Fridgen, who are bringing that price prediction idea to a new area: gadgets. Farecast, which was acquired by Microsoft in 2008, was a popular website that predicted when airline flight prices would be at their cheapest. Seattle-based Decide provides price predictions for laptops, televisions and cameras to start, and plans to expand to other types of products such as cell phones soon.
