Back in the day, we used to have PCs where we could replace any part of the CPU. We can upgrade only RAM to 16 GB or 32 GB. We can replace our hard disk with a new type of SSD. Sometimes it was even possible to upgrade processors.
Gradually, PCBs(Printed Circuit Boards) emerged. New techniques for including billions of transistors were developed. Chips started becoming smaller and smaller. We have power-efficient chips as a result.
In the name of efficiency, all the components such as RAM, CPU, and Graphics Processors were integrated into one single chip. This led to thinner devices and handheld gadgets, resulting in the loss of modularity.
From a software perspective, in the past, once when we paid for the software, then we didn’t have to pay extra for its lifetime. But nowadays, it is not like that. Subscription-based business models have become prevalent. They lock you into their echo system with their specific set of hardware. As a result, you will end up being a loyal customer forever since you can’t switch to other products easily.
Reintroducing the Modularity in Handheld Devices
Recognizing the drawbacks of this closed ecosystem, some people attempted to bring modularity back into handheld devices. One such device is called Mecha Comet.

Is Mecha Comet the first of its kind?
Not exactly. Previously, Motorola experimented with its Z series phones. LG also introduced the G5 phone with the modularity concept. Even google also experimented with modularity in the name of Project Ara. These devices allowed users to attach external modules, like speakers, cameras and battery packs. However, those phones somehow didn’t gain traction and were eventually discontinued. Those projects were short-lived and not widely accepted.
I believe the main reason for failure was those companies failed to build robust echo systems around it. Without a wide range of compatible accessories, users had limited choices.

What is the specialty of Mecha Comet?
Mecha Comet takes a different approach. Unlike other phones that rely on Android OS, Mecha Comme comes with Debian OS. The team behind the device worked hard to make the Linux Kernel work on such a platform. The Good news is that they said they open-sourced all of their work.
With Desktop class OS, Mecha opens up huge possibilities from a software perspective.
The Mech device is equipped with a 40-pin I/O connector. According to the company, this pin functions similarly to USB. You can detach the keyboard and attach the gaming joystick to this pin, the OS will immediately detect the new hardware.
Mecha Comet’s approach could mark a turning point in the tech industry. However, its success will depend on whether it can attract a critical mass of developers and third-party manufacturers to build compatible modules and applications.
Will it succeed in reintroducing modularity to the mainstream where others failed? Only time will tell.
