I have DAB
Bought for me as a christmas present.
Its rubbish. Bought it to listen to 6music at work mostly. Moved offices (to the one below) and now I get no signal at all. Note that I work in a city and I'm next to the window.
The secondary reason was to plug it into the car to listen to - again, no chance at all.
If I'm sat still, next to the mast (so I can get a signal) the bit rate is awful anyway. This isn't the sort of change that digital TV has brought us (better colours, more stable picture, more channels, dolby digital, HD etc) this is a serious downgrade!
