Language can be slow to catch up with changes in society, for example, we still talk about ringing someone up, even though phones no longer have a little bell attached as they did in the "good old" days, and we download "ring tones" for our mobile phones, even though half the time they are snippets of popular songs.  We also talk about dialling a number, although we no longer use phones where you have to put your finger into a dial with holes and move it round, but we don’t say we press or type a number, even though that is exactly what we do.
