People tend to upgrade their smartphones a lot. I think in the next few years a lot of people will upgrade their smartphone to a phone with 1TB of space. But, users with 1TB smartphones may still be using their old Windows 10 and older computer which may still have 500GB of internal storage space. Desktop and Laptop computers sometimes can last a long time, so some people may continue using them for over 5 years until they break. Chromebooks are becoming more popular, and most Chromebooks have only 16GB of space.
