I remember reading in The Times that, "Performing two Google searches from a desktop computer can generate about the same amount of carbon dioxide as boiling a kettle for a cup of tea, according to new research."
So why on Earth is Google now doing a search every time I press a key?! Not only is it very annoying, it's consuming my bandwidth and heating up the planet!
Please Google, stop it!
Just because it can be done doesn't mean it should be done.
