Two

One more sleep to go, though like a small child at xmas its very hard to sleep due to excitement.
The number two is brought to you courtesy of the coffee machine I will not have to endure any more. As someone involved with interface design and usabiltity it irks me that there is a 'no cup' button on this machine, but obviously also a 'cup detector'. If you try and get a coffee and put a cup under the nozzle it requires you to push the 'no cup' button. Conversely if you push the 'no cup' button without first placing a cup under the nozzle it refuses to vend.
Why have the button if you are not giving the user an option?
