Here is a fresh joke about OS, enjoy it

> What if Operating Systems were Airlines?
> 
> UNIX Airways
> Everyone brings one piece of the plane along when they come to the airport.
> They all go out on the runway and put the plane together piece by piece,
> arguing non-stop about what kind of plane they are supposed to be building.
> 
> Air DOS
> Everybody pushes the airplane until it glides; then they jump on and let
> the plane coast until it hits the ground again. They then push again, jump
> on again, and so on...
> 
> Mac Airlines
> All the stewards, captains, baggage handlers, and ticket agents look and
> act exactly the same. Every time you ask questions about details, you are
> gently but firmly told that you don't need to know, don't want to know, and
> everything will be done for you without your ever having to know, so just
> shut up.
> 
> Windows Air
> The airport terminal is pretty and colourful, with friendly stewards, easy
> baggage check and boarding, and a smooth take-off. After about 10 minutes
> in the air the plane explodes with no warning whatsoever.
