Love the idea (ish) and the form factor, I am a firm believer that a small and thinner (width not depth) form factor will be the future of phones until the next big leap, so a lot like this form factor, but with the ability to throw some LTE hardware in here and make a phone you can slap any pay as you go SIM in, I just wonder why not?
Btw this is not the future: https://techcrunch.com/wp-content/uploads/2019/02/ezgif-4-fb...
