This article talks about how Apple had to make many changes to the design of their pencil and iPad Pro. They wanted to add a special feeling when you use the pencil, called haptic feedback, but it was very hard to do. Also, they made the iPad Pro thinner than ever before, which was also difficult. The people who designed these products worked really hard to make them better and easier to use. Read from source...

1. The title is misleading and sensationalized. It implies that Apple had to reinvent the entire architecture of the Pencil just to add a single feature, when in reality, they probably made several improvements and updates along the way. This creates a false impression of how difficult or groundbreaking this feature really is.
2. The article cites an unreliable source: Numerama, a French technology site that may not have access to official or credible information about Apple's products. Using such sources undermines the quality and accuracy of the reporting.
3. The article focuses too much on the challenges and difficulties faced by Apple during the development process, rather than the benefits and advantages of the new feature for users. This creates a negative tone and perspective that may not reflect the true value or impact of the Pencil.
4. The article mentions other aspects of the iPad Pro, such as its thinness and portability, but does not explain how these features improve user experience or performance. It also does not compare them to previous models or competitors' products, which would provide more context and comparison for readers.
5. The article quotes a designer who talks about the original intention of the iPad as a "sheet of magical glass" that mimics paper. This is an emotional and subjective statement that does not offer any objective or factual evidence to support it. It also ignores the evolution and innovation of the iPad since its first release, which may have changed user expectations and preferences over time.
