I wonder if humanity will ever go back to Nokia times small phones. If this phone was 50% smaller, I'd buy it in a heartbeat. I don't want to carry these huge bricks anymore.
Since NASA demonstrates it is possible to keep servicing software on a 50 years old hardware, traveling into space far far away, I want someone to buy software and original tooling rights for the Nokia 1100. Then prepare a firmware upgrade for the variant with WAP capabilities to replace them with a more modern, very optimized, stack and have it installed on the (millions of) remaining devices. Then deal with carriers convincing them to provide ad-hoc 2G CSD service. Finally setting up internet services for the puny device. One can always dream.
Most people like big phones and they sell the best. With more people who only have phones as their devices, they want to have as much screen as possible.
The solution that I would implement ifI wanted a small phone would be a Motorola flip.
