mVox USB Speakerphone
Nice self contained, small, usb speakerphone
I bought this to use with my Mac for Skyping and Gizmo'ing.  I wanted something small and the optional headset jack was a plus for privacy.  Be aware that the headset jack fits your standard Cell phone headset, not a standard PC headset.  It works okay, as advertised.   <br />Positives:  Works with no drivers, small, sound quality is above average, better than the built in microphone on my iBook. <br /> <br />Possible negatives:  Draws too much power to plug into the usb port on my keyboard, and the cell phone size audio jack requires you purchase a cell phone style headset. <br /> <br />What I'm actually using now is a dinky, single ear/mic headset with a plantronic's usb headset adaptor.
