One way to look at the Mini is that it is a threat to cannibalize full-size iPad sales. The other way to see it is that the Mini opens Apple up to a larger potential market. I think the truth is in the middle. At the end of the day, as Tim Cook said: Apple can't fear cannibalizing their own products because if they don't do it someone else will. It's a balancing act to be sure.
Thats an interesting perspective - I wonder how Jobs would have attacked the same problem. I've never known Apple to focus on consumer demand as much as they are now. It seems that Apple would always put out a product and tell/market their story that this is the only way this product should be - anyone else is telling you differently does not know what they are talking about. I'd love to know how Jobs felt about a smaller iPad.I mean, they exploited an entire segment (tablets) when nobody was demanding such a product, nobody thought they needed/wanted such a product. The essentially proactively told the market what the market needed - instead of reacting to the market and competitors.
Iphone was another example where someone at Apple had an idea and built it before there was really any consumer demand.
If I was still a shareholder, I would be worried that they are becoming more like their competitors - and playing catch-up to consumer demand, rather than creating consumer demand. The value is in creating demand, not chasing demand - at that point almost all competitors are on equal footing, and then its just a race to the lowest price point (lowest margins) - and that hurts profits.
