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".
