Kabn said:i was going to get that, but i just didn't like the color thing. and it has the same refresh as the MX500.
and i've played with an MX700. couldn't tell a difference from a wired mouse. it just costs more and requires charging or switching of batteries, which i would invariably forget.
I think the 510 is going to start coming with different color plates...... either that or jump up to an MX1000 I really do love mine.
