The sales might not but the customer satisfaction polls do....
Apple slipped in customer a satisfaction poll.
Only marginally, real sales are a bigger indicator of success and consumer opinion than satisfaction polls that no one is ever quite sure how they are collated. I mean have you ever been asked or know anyone who has been ? Likewise if people are not satisfied, why are they still buying in droves and yet those supposedly more satisfied are not buying (with less than expected sales) ? It's all highly questionable and certainly not indicative of any true trend or science.
