Important:
 
 The only noticeable physical difference between this model and the earlier G4 
model is the appearance of the foot sockets. Check the foot sockets on the bottom case to 
see this difference. For this model, the foot sockets are uniformly flat with no dimples. 
However, the foot sockets are compatible with earlier models, so this physical difference is 
not an absolute indicator of the model type. Be sure to con firm the model type using serial 
number veri fication. 
iBook G4 (Early 2004): Foot sockets include three dimples
