Throughout the day, readers have been sending in tips about the missing iSight. When I checked this evening, Apple's store was willing to sell me an iSight Accessory Kit, or a Griffin SightLight, but the actual iSight itself was missing in action. Some readers have reported that their local Apple Stores are out of stock as well. Reader Richard Cook checked CompUSA, MacMall, MacZone and MacConnection. All out of stock with a 10-14 day wait. So why has the iSight disappeared? Could we be looking at a new product announcement? Might a new iSight be introduced soon? What do you think?
