mVox USB Speakerphone
Hands off, plugin, talk, listen simple
I do a lot of work with Europe.  That means late at night with strange accents and languages.  Not the time for complex interfaces. I need something that keeps my hands free when I skype these guys and allows me to discuss problems with both hands.  I am not a technology genius.  I bought the MiniVox because I was assured that it plugged in and worked immediately, and it did!  This thing is a no brainer for no brainers and I recommend it highly.  You can even plug in a headset for those quiet sessions.
