hi, im getting a wireless mouse for my laptop. im looking at m325 and m310 at the moment and they are both arnd the same price.

which one u all would recommend ?

is it true tat m310 has 3 buttons (means the mouse scroll is click-able rite?) and m325 only has 2 ?

m310 is laser mouse, m325 is optical mouse, any difference between them ? thanks...
