Apple recalls batteries as well.
Sony's defective batteries - over 4 mio of which have been seen recalled by Dell - are in some of Apple's notebooks as well. Some 12" iBook G4 and 12"/15" PowerBook G4 models are affected. You can check on
this Apple support page. 1.8 mio Apple notebooks are affected, no version of the MacBook and MacBook Pro, though.
Sony is facing huge financial trouble because of it. Dell has taken a lot of bad press lately. The question now is how the press reacts to Apple's "news".
