Hi Clive,

FWIW, for the first six(6) months (or so) that I had my iBook I would always "turn it off" and
then restart it again, contrary to the opinons of a number of people I knew. So, one time
when I knew I was going to need to use it with in a few hours and I put it to (err ... in) sleep
mode and have continued to do it that way for the past thirty-two (32) months

... mind you ..

....mine's a Mac and doesn't have Vista

Cheers,

Jack
