Some posts mentioned good reasons for continuing to use XP or maintain backwards compatibilty: If it makes development of LFS easier and allows WINE to work that are perfectly valid reasons.
Similiar with some systems/machines in industrial use where upgrading is not easily possible because production must go on.
(Although I see no good reasons for switching off security updates?)
But: That is all very specifique decisions made by technical peoplepersons.
Such users have the knowledge to keep their system secure. (or can wage the risks, as there is never 100% security)
Problem is most users are not like this:
Many happily double-click on holiday.jpg.exe to see the picture.
Or want to download some file and get fooled into installing some download-accelerator-whatever-trojan.
That does not even cover the more subtile infection forms.
How else can worms like http://en.wikipedia.org/wiki/Conficker spread to million of computers?
In tech-orientated forum such as this one it is hard to imagine but not everybody is so good with computers.
