A mouse that does not shine in the
dark :-) at least optical ... but preferably with a central wheel for zooming
For a mobile dome, I would advise
the use of a trackball to avoid sliding into an ondulated surface.
I myself have tested a wacom touch
pad with Linux.
Very nice and pleasant but a little
tricky in the dark because of the pen and precision click.
The result for me is that the mouse
(as long as you get used to this "special" movement under a dome where
right turns into a curve ...) remains the best tool.
And though I shelf oriented in the
cardinal points and reversed the left / right to push the stylus on the
right, the mouse goes in the same direction on the screen. In fact the
problem is that you use to be concentrated to what you are doing by looking
at the shelf and not the screen. And if you look at the screen you don't
know where you move on the surface.
Also when you click to highlight
an object, generally you move slightly and this time it's the scenery that
shift. Heartache guaranteed.
