I can see it now, or rather hear it. Railway carriages, cafes and offices, all full of wankers shouting at their PCs, even louder than they already do at mobile phones:
"No, I said 'science', not 'seance' you stupid bloody thing!" No -- don't write that! I said don't -- aaaaaaaargh!!"
Bang, crash, PC out the window. Maybe it is a good idea after all.
