I have enough money to buy the 8GB Touch, and was wondering if it was worth the extra £50... I like to play lots of music, and hate bad sound quality. The app's are making me swing for the touch, but I don't wanna go for the touch just for app's. I don't really watch many movies on the go, but it would be nice to have something to entertain myself on those long car/train journeys. Is there any like "OMG, THIS IS AWESOME" features on the Touch which makes it worth the extra £50? Thanks.
