My dad used a Tandy Dreamwriter for many years to write on while working as a travel journalist, well into the 2000's.
Small, Z80 based, with a few lines of text on the screen and powered by AA batteries. Other journalists used to laugh at the 'old guy with the Fisher Price computer', but the instant-on and distraction free typing was a definite advantage. Pretty nice not having to worry about a fragile, expensive laptop while out in the jungle or whatever, too.
