With OS2008, you don't need one. Gizmo v4.0 on the PC supports video chat, as does the new Gizmo client on OS2008 (which is now available on both N810 and N800). I put together a video demonstrating this over at Tablet-Guru.com, and please feel free to use your N810 or N800 with OS2008 to give me a video call over Gizmo: grcadden. http://www.tablet-guru.com/2007/11/g...video-calling/
