If you also like to be able to connect with your laptop while also on the move, Vodafone and other mobile operators have invented an ingenious device: the 3G Data Card. This small memory-stick-like device attaches to your computer and delivers a cybernetic connection almost as speedy as broadband at home. Remarkable little thing – you’ll never again need to search in vain for a wireless connection to send a hefty attachment. They are available at most London mobile phone shops (e.g. Carphone Warehouse).
