I think the next iPhone won't be called the 'iPhone 4' that would be confusing.
Maybe they will call it the 'iPhone 4 II'
Seriously, I don't think you youngin's get it.
Apple doesn't compete with anyone.
They just do their own thing.
Really.
For the first fifteen years they didn't even have commercials.
Then when they did, they just did them for fun.
You see how they show them off at the keynotes.
They are so proud of them. They don't even try to sell the product.
They just point the camera at the new thing and spin it around.
And Cut!
They don't care about Android, they don't even care about stock prices or profits.
I have never seen any change in how they act.
The first 10 years of Apple's existence they were drowning in money
Then in the mid nineties they had only a little to work with.
Now they are drowning in money again
I saw no change in their behavior at all.
They just make fewer mistakes now.
And as always, they do their own thing.
