That's speculation. $700 is quite far in my opinion. Not that stocks always grow like that anyways.
Apples riding the bull and the only I think that can stop them is Apple themselves.

10% of my checks went into the stock plan for 4 years
Actually the only thing that might stop Apple is the US Government. It's not been getting much attention but the investigation in to price fixing eBooks could lead to an Anti-Trust lawsuit against Apple similar to what happened to Microsoft. That would be bad.
Microsoft owned almost all the marketshare. Except for the iPad Apple is not the marketshare leader. Apple just knows how to make more money with less marketshare. But the Government could go after APPLE you are right.
