Voip telephone in a mouse

I got this by e-mail from a Chinese company advertising it as “the worlds first VoIP telephone mouse”, which of course is not true.
The only problem I see with both is: what if I want to use the mouse while telephoning?
At the moment we can only really let the picture speak for itself, as nobody seems to have had one yet. I should be receiving a sample in the next few weeks and then will follow up with a review of this gadget that will do one thing for sure: make your coworkers a little bit confused and maybe even amused.
