I had this iBook for 18 months now, and the battery life has been around
3 hours. Now I started to get 4, 5, and believe or not up to 6-7 hours
and it seems to be going up with each charge. Can't complain, but I'd
like to know what the heck is going on.

Actually your battery life is not increasing; what's happening is that
hours are getting shorter. This happens every year as winter approaches.

Maybe he's traveling very fast, so time is slowing down due to
relativity.

If the iBook was travelling with him, their relative time should
remain the same. But to an external observer it should appear
as if time had slowed down.

Two possibilities, perhaps working in concert:
1) Your usage patterns have changed in such a way that you're demanding
less of the machine than you used to.
2) The accuracy of the estimate has changed.
Are you actually getting the times you note, or are you reporting the
estimated time the machine tells you?

they all default to going into a toilet. However, a person can redirect his
"standard output" to somewhere else, if he so chooses. - Jeremy Nixon
