I like terminal. I use e-mail, browser etc on terminal but my terminal are big and heavy.
I need network and keyboard. Similar:

Many people using powerline and nerd font. I need only ssh, vi, ruby and mc :wink:
And day working device, not 3h but whole day.

Lichi working with minimal power, please add keyboard , small screen (meybe e-ink or better pixelQ)
and network. Look at pine64 laptop. 10h working device with linux.

you can use small bt keyboard & small oled lcd, it should easy to drive
