Pros: Logitech!
Cons: None.

Works perfectly with my Pentium 4 desktop. The built-in microphone with RightSound technology worked as advertised. Works fine with XP. Tried on my laptop running Vista with no problem. You just need to install the software first.

The RightLight technology really gives superior video performance in low light situations which is very important for me because of my eyes.

Got no issues with MSN, Yahoo or Skype.
