Using US Electronics in England - Concerns About Electricty and Adapters

The question arises if one can use their US purchased electronics in England. For example, last year I brought my iPod Shuffle from the US to England. I found that it wasn't too much of a problem to and long as I used the US-to-UK prong adapter. If you are having trouble with this apple product, you can call 1-800-my-apple. If you are visiting make use of a step down power converter, unless the dock will convert the voltage from 220 to 110v. For electronics you must really have a step down converter and engineered in stabilizer.
