The lessons from MIDs' modest market penetration—due to high costs and underdeveloped apps—fueled strategic shifts, including subsidies that lowered entry barriers and spurred the global tablet market to reach approximately $66.6 billion in revenue by 2020, reflecting a 1% year-over-year increase amid rising demand for portable computing. These dynamics also inspired flexible form factors in later innovations, such as Samsung's 2023 Flex Hybrid display, which combines foldable and slidable elements to expand from phone to tablet sizes, echoing MID principles of adaptable portability. This trend continued into 2024 and 2025 with advancements in multi-foldable devices, further blending smartphone, tablet, and laptop functionalities in line with the original MID vision of versatile mobile computing. Beyond technical and economic influences, the development of portable internet devices like MIDs contributed to culturally normalizing always-connected portability, embedding the expectation of ubiquitous internet access into daily routines and foreshadowing the hybrid work models that proliferated after the 2020 pandemic. By integrating Wi-Fi and cellular connectivity into pocketable devices, such devices shifted societal behaviors toward constant online engagement, boosting the use of remote tools like video conferencing and cloud collaboration platforms during widespread lockdowns. This normalization enhanced productivity in distributed environments, with portable devices facilitating a 19.5% surge in tablet shipments in late 2020 alone, as users adapted to virtual workflows.
