I see we have the classic "shareholders" defense when it comes to the accusation of greed on the part of Apple. Let's just reword things, shall we? One of the greatest signs of mismanagement at Apple has to be the iPad line. Since its peak in 2013, Apple is now selling less than half the amount of iPads. As a result, the iPad is generating significantly less profits than it was in 2013. I think it's safe to say that this isn't to the best interest of shareholders.
If Tim Cook had the fortitude, he'd create a team dedicated to designing iOS for the iPad. This team would be designated with the task of developing iOS to be better suited as a device for professional use while maintaining the iPad's current ability to consume. This would involve trackpad support as well as the ability to plug into monitors.
The iPad *is* a powerful computer, and if Apple took proper steps it could replace laptops/desktops for large portions of consumers and professionals. The problem is I don't think Tim Cook can stomach the risk that would involve. He'd see such a team as an unnecessary expense, and the R&D required would be considered too risky. He's a CEO mainly for maintaining the status quo which would be fine for Coca Cola, but not in the computer industry where you need to be a couple of years ahead of the competition.
