But do phones have to be so powerful? If they are dumb terminals, could we get smaller form factors, longer battery life and make them more disposable for the billions of people that cant pay $$$ for a device?
Maybe something like a kindle but with apps like WhatsApp, Twitter etc. optimized for e-ink displays.
I saw a kind of interesting device recently with a regular screen on the front and e-ink screen on the back, the Yotaphone 2: https://yotaphone.com/gb-en/
Very cool, I think.
