It would be easy to look from the outside and wonder why so many people are happy to upgrade from a high-end smartphone to a newer model with a slightly faster processor, slightly better screen and differences that look minimal to the outside world. These changes look like little more than vanity or obsessive behaviour on behalf of the purchaser, but there is a deeper story to why people are happy to continually upgrade their smartphones.
When you use a product so often and for so much of each day, small changes can mean big improvements in efficiency, ease of use and greatly enhance the overall experience. A slightly larger screen makes web browsing more practical, a faster processor means that you can do even more with your smartphone and a new design makes everything feel fresh.
Chances are that a smartphone is the most used computing product for most people and thus it makes perfect sense to always have what the individual considers to be the best. There is of course a small amount of simply wanting to own the best, but it is likely that wanting a better product to perform multiple tasks on is the main justification for continual upgrades. And that makes perfect sense.
