As Alan said, some of the symbols are in strange places, but it is still
the same basic layout. I even used mine for a while with a US keymap,
but I now have the proper layout (http://swan.ml.org/pc110/pc110.keymap)
so when I need something obscure I don't have to try to remember where
it would normally be. The main problem with the keyboard is not the
layout but that it is so small---there is no hope of touch-typing on it
and I usually end up just using my index fingers. On the plus side, the
whole keyboard is smaller than my hand-span, so typing ctrl-alt-whatever
one-handed is possible! The tiny and displaced right shift key is
a bit inconvenient too, but you do get used to it. I can enter text
reasonably quickly now, but C still slows me down as it uses a much
richer set of symbols.
