What's the whole DAB / FM thing? We live in an area where a mobile signal is like gold dust and have heard digital radio is hit and miss at the best of times. Want to get DH a radio with alarm for Christmas or one to have out in the garden - solar maybe? Want one that looks good - he's a designer and like classy styling. If I just get an analogue will it be useless in a couple of years? What's the latest?
