I have downloaded an 'app' for my Iphone which means you can talk to it in order to start a Google search.
You simply press the button and say 'spoons', or 'bucket' or 'Godalming', or indeed whatever you are after. I suppose it is handy if you are out an about in a city and don't want to stand about typing. It's rather good!
I haven't managed the Holy Grail yet - Classic Doom for Iphone but apparently it is in production!
