Apple problems buried in online sales, study concludes
The big thing appears to be that noone wanted to buy a Mac in July, in anticipation of the Macworld NY announcements. Of course! And after the announcment there was nothing shipping immediately.
I bet this will bite Apple's ass in the X-Mas season too, people will be waiting for Macworld SF. Apple should schedule their next hardware rollout for November or very early December instead of MWSF so they don't get hit again.
The timing of those two events isn't very good.
