2. O'Donnell Abu and other scary tunes emanating unbidden from people's jackets and pockets.
3. Sudden, disconcerting shrieks from the seat behind of: "Hiya, I'm on the bus.".
4. Having to travel second class on the Belfast train to avoid the cacophony of loud businessmen doing their business.

6. Nervously eyeing my attractive companion's mobile on the restaurant table in case it rings and she's abruptly whisked away by some idle chatterer.
7. Having a peaceful solitary lunch when two eager youths place their new mobiles on the next table and set about comparing their portfolios of new ringing tones.

10. Trying to hear urgent calls which sound as if they're coming from a bathysphere several fathoms deep and sinking fast . . .
