Matches fine with Asus EEE PC 1000, but sits and does absolutely nothing on Skype for example...I purchased the Plantronics Voyager 510 because it doesn't have any wires to break from their constant flexing...I did not care that it is mono, not stereo, I wanted it to use with Skype.It is possible that there is some complicated way that only a true geek can figure out to make it work with my Asus....I have neither the time or the interest to pursue...I wish I had not listened to all the hype and just stuck with my old IBM T23 / XP SP3 and "Antivir" free antivirus,which works perfect and definitely does not have all the problems these 2 electronic devices have
