I wanted to post this earlier, but I didn't want to take focus away from my XBox360 post.
Anyway the UK now has it's very own Google Maps UK.
This is great, but what is even better is Google Maps UK Local where you can type in your postcode and a keyword. Like Pizza, Library, McDonalds, Taxi, School, pub, museum or anything else you like, and it will locate the nearest relating destination, display it on the map, give you a list of all the ones it found in order of nearest first, WITH the telephone number!
Now if that isn't fun and useful, I don't know what is.
