They have made the EXACT same arguments since after the iPod.
The Zune was to kill it, cheap alternatives were going to kill it. Didn't happen.
Then they put out the iPhone.
It was doomed, they said at first, then Android was going to kill it, then the Antennagate, then the 4S was not impressive enough, etc.
Then the iPad came out, and at first it was "just a large iPhone" and it will fail, then it was gonna be killed by Windows tablets, then by Android tablets, then the Kindle Fire.
They never stop in the same bloody vein. How about instead of BS predictions they do some REPORTING?
I.e tell how Apple does based on numbers, and report it when they --inevitable at some point-- start losing out? Why do they feel they have to play prophets?
