I noticed yesterday that the world's major mobile phone manufacturers have reached an agreement to standardise phone chargers across all models and all brands. One charger will then be able to charge any phone.
All I can say is "it's about bloody time". It always seemed the incredible waste, stupidity and excess that each time you bought a new phone, the charger was different. I have a box full of the things sitting in my attic... it seems such a waste to throw them out, but, of course, the phones they belong to have long gone.
My only hope is that laptop makers follow the lead.
