If you think you have to spend hundreds of dollars on a smart phone for your kid or your parent, or even for yourself unless you are the hoity toity type, think Blu and think $50. They aren't the greatest phones, and the camera and sound aren't so hot, but they're not toys and they function pretty darn well. Here are links to a review in the WSJ and to see them at Amazon.
