During Apple CEO Tim Cook's talk earlier this week about expanding the company's Ireland operations, he criticized Microsoft's new "diluted" Surface Book hybrid as failing to combine a tablet and notebook into an effective hybrid. Meanwhile, his company just launched the new iPad Pro this week, which is a supersized tablet computer equipped with a keyboard and stylus accessories.

Apple is marketing the new iPad Pro as a tablet, according to Engadget. In fact, the device's keyboard and stylus are less required than the Surface's keyboard covers.

However, Cook recently claimed that many people are using the iPad Pro to replace a notebook or desktop. On the other hand, several reviews have argued that tablets cannot replace laptops yet.

The criticism of the Surface Book by Apple's CEO seems serious because he has described his company's relationship with Microsoft as excellent, according to The Verge. In 2012 Cook criticized tablet-laptop hybrids by claiming it would be like combining a toaster and refrigerator into one product.

Cook's comments were mocked by Microsoft at a Surface event during last month. This was after Apple had paradoxically announced the iPad Pro's laptop-like larger display, keyboard, and stylus.

It is possible that the iPad could later be considered more like a hybrid laptop. That could happen as iOS apps get more complex.

However, the iPad Pro's operating system is still tablet-based, and it contains no mouse input. It is still far from being a laptop.

Several media outlets have argued that Cook might not oppose the Surface Book itself. Instead, the criticism could be based on its function as competition in the race to perfect a tablet-laptop hybrid.
