My question is kind of mundane. Is the power supply removable with a standard DC connector or is it built into the device? The reason why I'm asking is that I'd like to purchase one for my mother, but since she lives in Australia the plug will be a problem unless I use a converter - which has the potential to cause problems for her (as she's not too tech savvy) and it would be easier if I go find a suitable power supply.
