well theres the iSight which will match your PowerBook but its HUGE and discontinued. i suggest the Logitech QuickCam Vision Pro which is a lot smaller, will clip onto your lid easy and is made for Mac so know installation needed!
Well both those look great, but this is going to be a Christmas present. And i was only kind of looking to spend 50 dollars or under. But if worse comes to worse i guess I'll have to spend that much, but yeah any other suggestions?
