I think your prediction is very conservative, if we have a strong market correction over the coming weeks and months this stock could go much lower to the range of $130-$220, competitions from others is very strong in particular Google, Samsung and Microsoft. Samsung is the leader, this is what I see on the street and in the shopping malls, Apple is history by now.
The stock already has '$150 cash per share. $140 Billion cash the co. has divided by 0.94 Billion shares outstanding. So for anyone to say the company is only worth '$130 - 220 per share is pretty ridiculous. They could close the co. down today, make believe the leading high-end smartphones sold on the planet with over 50% of market share in USA are worthless, same with IPAD, and still give you $150 cash
