In that case why don’t they have a back facing camera with three lenses and a flash just in case someone wants to take a picture on vacation with their MacBooks? I guess they should also have an accelerometer, a gyroscope and a gps chip just in case I need to use it for directions....
I guess this is more a rhetorical question as taking pictures with a back facing camera is an extreme^10 edge case while doing video calls with the FaceTime camera for most users is a daily or at least weekly occurrence.
Why not? Apple sells ~200M iPhones a year, so they already are ordering millions of FaceTime cameras for the iPhones. Why not buy 10M more of the same model and put them in the MacBooks?
Just to be clear, I don't think Apple should put a back facing camera into their laptops. However, they should consider updating the FaceTime camera as it is regularly used by most people.
