I just can't bring myself to believe this part :

"Psion developed the user interface, codenamed Hildon after the bottled water, on which Nokia would base a range of Symbian products.
(...)
Today, the user interface lives on almost unchanged, in Nokia's promising Linux-based Tablet, and the (now) open source user interface API still bears the Hildon name."

A Gnome-based GUI descended from Psion by way of Symbian ? Bottled water ?

If this isn't a hoax, it's definitely the funniest (and most ironic) thing I've read this year...
