Why computers are like men:

In order to get their attention, you have to turn them on.
They have a lot of data, but are still clueless.
They are supposed to help you solve problems, but half the time they are the problem.
As soon as you commit to one, you realize that if you had waited a little longer, you could have had a better model.
Why computers are like women:

No one but the Creator understands their internal logic.
The native language they use to communicate with other computers is incomprehensible to everyone else.
Even your smallest mistakes are stored in long-term memory for later retrieval.
As soon as you make a commitment to one, you find yourself spending half your paycheck on accessories for it.
