The IBM 5100 is pretty neat; I have a few of them. But it most definitely wasn’t the first portable computer. HP offered the HP 9830A desktop computer in 1972, vs. the IBM 5100 in 1975.
The HP 9830A was of a similar physical size to the 5100, and weighed less. It ran BASIC, and had a one line text display rather than the 64×16 CRT of the IBM 5100. It also didn’t have as much memory as the IBM 5100. Nevertheless, it was a complete computer.
$20K in 1975 was about like $80K now.
