"These models have been supported for at least 14 years -- some as long as 18 years -- but technology has come a long way in that time, and these devices will no longer be supported moving forward. We are notifying those still actively using them and offering promotions to help with the transition to newer devices."

Compared to most tech, Kindle users enjoy a more generous period before their devices stop receiving support. While most tablets and smartphones receive 3-7 years of software updates, Kindles often see 8-15 years before major cutoffs. Kindles also have a loyal user base, with many people enjoying a single device for around a decade.

The key difference between a Kindle and other tablets is that the former is a single-purpose device. Its nature doesn't require a fast processor or high-end display -- a Kindle from a decade ago can still display books perfectly fine today. Compared to tablets, which have to adapt to more demanding apps and evolving camera, AI, and operating system features, Kindles don't depend on cutting-edge hardware.
