Wow. Why can you not grasp that many users would like a larger display that still fits in a pocket?
Why do they want a larger display that fits in their pocket?
Let me break this down more.
Why does someone want a car that turns into a plane?
Why does someone want a lawnmower with wings?
Why does someone want a laptop that turns into a tablet?
Why does someone want a desktop computer that folds up into a portable laptop?
Why does someone want a 50” TV that rolls into a small tube case?
Etc.
The point is, which I keep repeating: 1. These convertible devices compromise their primary and secondary function where they are worse than their dedicated versions. 2. People use a tool or a device that is purpose built and purpose designed for that purpose.
Some discussion. People do not use a 50” screen and mouse standing in line at Costco because that use case makes no sense. They use a smartphone. They may wish they would have that for what they are doing at that time (e.g., daytrading), but they need a portable device like a smartphone that has tailored interfaces and interactions for that small screen and form factor and can be used with one hand.
A tablet also doesn’t make as much sense in use cases calling for smartphone portability. There also seems to be this idea that there is such a critical demand for tablet use cases. There isn’t. Tablets peaked long ago and have always been a subset of the smartphone market.
Studies and market research shows that tablets have a narrow set of use cases for people, which has expanded a bit due to them becoming more capable for productivity. But they are more awkward to hold in the hands and less efficient to interact with because the screens are larger and require both hands to use.
If we take the use case of a person commuting for work… on a train… would they want to fold their phone out into a tablet? You may think they could be productive working on the train… What about a keyboard? That has to be a separate item for them to carry. And the tablet itself as I have repeated many times is compromised. And the tablet does have to compete with the smartphone. With the advent of larger screened smartphones, the use cases and value of a tablet got diminished. Many people don’t use or want a tablet.
The same can be said of convertible laptops. People use laptops for specific reasons. To make a convertible laptop, it compromises the laptop and tablet where it becomes worse at both of these dedicated devices.
The push for a larger display that folds into a pocket-sized device is really just the latest version of trying to make one tool do two jobs poorly: like a car that turns into a plane or a laptop that doubles as a tablet.
Dedicated devices succeed because they are purpose-built: smartphones are designed for mobility, one-handed use, and tailored interfaces, while tablets fill a narrow, secondary role that has already been diminished by larger smartphones. Forcing the two together doesn’t create a superior experience; it compromises both, leaving users with a device that is less effective than either of the dedicated versions it tries to replace.
