Comment The REAL problem (Score 1) 220

Spectrum? Bandwidth? Everyone seems to be forgetting the real limiting factor with cell phones... Battery life. All these fanciful ideas on what a cell phone can do or go about doing it will take power. Without a giant leap in in battery technology, you are just wishing in a jar. The amount of energy needed to support all these wonderful ideas has to be portable and last longer than two days between charges before anything can be added to current cell phone technology. How long has the electric car been waiting for battery technology to get up to a point that a car can travel 40 miles on a single charge? We need a breakthrough in battery technology before we need a breakthrough in cell phone technology.
