Congrats on making a product. I see the appeal of these products because they embrace the productive aspects of technology and prevent the intrusive attention seeking technologies from being involved.
The reason I would not get a device like this is because the device I have is already capable of doing all this. The problems that hamper my productivity are psychological and unless I’m going to completely get rid of all the devices and thoughts that are distracting me, I don’t see how another device is going to help me. In fact, I can see me being more unproductive just trying to get every little thing right with synchronization and using the product versus just doing the thing I should be productive at.
I really do like the aesthetic though. It’s a hell of a thing to build your own hardware and software and I hope it helps others and can grow.
