Introduction of DAB is a classic case of technological determinism. It might help kill air-broadcast radio but it won't take over from FM in a million years.
DAB will never achieve the level of market share to replace the competition, because it does not address the needs of a significant proportion of listeners. It is not usefully mobile, and cannot service those who still listen to radio in preference to the plethora of alternative audio sources. In between things like high-bitrate mp3s, podcasts and internet streaming radio (DRM aside), DAB falls sadly short of two things FM excels at - being easy to tune into with a low-cost device and the potential for high quality sound.
There is not yet, and probably never will be, a tiny DAB receiver that will work on a beach, a bus or in your pocket, at all or for a reasonable length of time - not startling miniaturisation, after all there was all this for FM way back in the 1970s. DAB is apparently never going to work properly in the car, or at all for 10% of the population. The boxes won't get much smaller, or cheaper, or more economical, as potential sales won't justify the development and production costs. Do they have DAB in China?
Quite likely many people are tempted, even me, even now, to buy one: personally I quite like the idea and it's certainly an interesting gadget - blue LED displays and an audio transducer as well as radio 4 (sometimes). I am not overly concerned about the lack of sound quality, as I would mostly listen to talk and over ambient noise. However I would find it really difficult to justify the spend on what, with its dwindling market share, is rapidly becoming a niche for late/early adopters and curiosity collectors; as well as the evidence of the German experience it just seems fairly obvious by now that the whole DAB phenomenon is on a one-way trip along the way of 8-track, Betamax, HD-DVD et al.
Paris because she is dumb enough and rich enough to buy one.
