I'm having trouble seeing all 15 buttons on it...where they hiding?
On top:

2 "normal" buttons
1 button that is also the scroll wheel
2 buttons directly beneath the scroll wheel
2 buttons, one on either side of the scroll wheel between it and the "normal" buttons

Total 7

On each side:
Two thumb/pinky buttons
One rocker switch (counts as two buttons as you can rock it forwards or backwards)

Total 8 (4 per side)

For a grand total of 15.

Personally, I think my 7-button Razer mouse has enough... and I only use 5 of them anyways.
