iPad Pro (2017, A10 series) vs iPad Pro (2018, A12 series)

The iPad Pro 2017, released in June 2017, and the iPad Pro 2018, launched in October 2018, represent two consecutive generations of Apple's premium tablet line. While both devices offer a powerful iPadOS experience, the 2018 model introduced a significant design overhaul and substantial internal upgrades. Key differentiators include the 2018 model's edge-to-edge display, the removal of the home button in favor of Face ID, and a shift from the Lightning port to USB-C connectivity. Both run on Apple's iPadOS, providing a consistent software experience, though the newer hardware in the 2018 model allows for extended software support and enhanced performance in demanding applications.

When considering the practical lifespan of these tablets, several factors come into play, including their release dates, expected software support, and repairability.

• Release Timeline: The iPad Pro 2017 was released in June 2017, while the iPad Pro 2018 followed in October 2018. This difference in release year means the 2018 model will generally receive software updates for a longer period.
• Software Longevity: Apple typically provides iPadOS updates for 5-6 years from a device's release. Given its later launch, the iPad Pro 2018 is expected to receive at least one additional year of major iPadOS updates compared to the 2017 model, extending its functional lifespan for modern applications and security features.
• Repairability: Both generations of iPad Pro have historically received low repairability scores due to the extensive use of strong adhesives, making internal repairs challenging. While the 2018 model introduced some design changes, the fundamental difficulty in repair remains similar across both, often resulting in a score of 2 out of 10.

The performance of these iPad Pro models is largely determined by their internal processing capabilities, impacting everything from everyday tasks to intensive creative work.

• Processing Power: The iPad Pro 2017 features a processor that handles multitasking and demanding applications efficiently. The iPad Pro 2018, however, includes a newer generation processor that offers a notable increase in speed, particularly for graphics-intensive tasks and multi-threaded operations. This translates to smoother performance in professional creative apps, advanced gaming, and more complex workflows.
• Storage Options: The 2017 model was available with up to 512 GB of internal storage. The 2018 model expanded these options, introducing a 1 TB storage tier, providing significantly more space for large files, applications, and media.
• Battery Behavior: Both models are designed to provide up to 10 hours of web browsing on Wi-Fi or video playback. While the 2018 model's processor is more powerful, its efficiency improvements generally allow it to maintain similar battery longevity under typical usage scenarios.

The display is a central feature of any tablet, and both iPad Pro models offer high-quality visual experiences with some key distinctions.

• Display Technology: Both the iPad Pro 2017 and 2018 models feature Liquid Retina IPS LCD displays with ProMotion technology, offering a 120 Hz refresh rate for fluid scrolling and responsiveness. The 2018 model's display is often referred to as a 'Liquid Retina' display, which is an advanced LCD panel.
• Resolution and Clarity: Both generations maintain a high pixel density of 264 pixels per inch (ppi), ensuring sharp text and clear images. The 10.5-inch 2017 model has a resolution of 2224x1668, while the 11-inch 2018 model has 2388x1668, and the 12.9-inch 2018 model has 2732x2048.
• Design and Viewing Experience: The iPad Pro 2018 introduced a significant design change with thinner bezels and rounded screen corners, allowing for a larger screen in a more compact body compared to its predecessor. This edge-to-edge design enhances the immersive viewing experience.

The camera systems on these iPad Pro models are capable for a tablet, with the 2018 model bringing notable advancements, particularly to the front-facing camera.

• Rear Camera System: Both the iPad Pro 2017 and 2018 feature a 12-megapixel rear camera with an f/1.8 aperture. The 2017 model includes optical image stabilization, while the 2018 model uses automatic image stabilization. Both are capable of recording 4K video. The 2018 model can record 4K video at up to 60 frames per second, an improvement over the 2017 model's 30 frames per second.
• Front Camera Capabilities: The iPad Pro 2017 has a 7-megapixel FaceTime HD front camera. The iPad Pro 2018 upgrades to a 7-megapixel TrueDepth camera, enabling Face ID for secure authentication and features like Portrait mode, Portrait Lighting, Animoji, and Memoji.
• Audio Quality: Both generations feature a four-speaker audio system that adjusts sound based on orientation, providing a rich audio experience for media consumption. The 2018 model also includes five microphones for improved audio recording and call clarity.
