According to my mobile phone, it's four minutes to eleven in the evening here in Britain.

I don't have a watch. That's why I look at my phone to find out what the time is. So do millions of Americans my age.

The mobile phone has changed the race for the White House. Firstly, without the humble cellphone, the White House would have been hit by the fourth plane on 11 September 2001. Secondly, if John Kerry wins the White House this evening, the reason we won't have seen it coming is that so many young Kerry supporters were unreachable by the pollsters, who largely use landlines.
