I am glad that you are happy with your iSight! Be sure to check out a great little add on called iGlasses. It is like the preferences panel that Apple "forgot" to include with the iSight. In particular, you can use it to increase the gain on the camera in low light situations, dramatically improving the visibility of the image. By the way, I am not affiliated with iGlasses in any way, just a very happy customer.
