The new Magic Mouse is so slippery that I feel like I have to hold it properly because otherwise it slips away (“with an optimized foot design that lets it glide smoothly across your desk”). Maybe it's just because it's new. But it bothers me.

That the logo at the bottom of the Magic Mouse is missing, I don't know what to think of it. Apple could at least state it correctly in the product description.
I'll return it.
