New use for post boxes…

I read on The Register that Spectrum Interactive are putting wifi hot spots into old phone boxes. Neat idea, not sure how useful it is unless you can sit somewhere nearby but it might work. However I had another idea. I’m currently sat in Starbucks where for the cost of a cup of coffee I am charging up my phone and laptop. So… why not public use power points in old phone boxes? You could sit squashed into a phone box doing some surfing while all the gadgets that you need to run your life get juiced up for another 8ish hours of 21st century life.
