Microsoft plans to revolutionise the mouse on 9 September

In a coincidence of the date, Microsoft has scheduled a press announcement on 9 September, when Apple is expected to present its new iPod.
Wanting to tease us, Microsoft merely published the following image inviting us to say goodbye to later.

Alas, Amazon Germany seems to have let the cat out of the bag and showed what should be announced.

On September 9th, Microsoft will present the first mouse without a red LED or a invisible laser, but with a blue LED which is expected to further improve the functioning of mice especially on difficult surfaces.
The future will tell us whether this new diode actually improves things or whether it is merely a way for Microsoft to set themselves apart from the competition.
