It might be a stretch to call Personal Spy Terminals "computers".
Live distros
Puppylinux, wifislax, porteus.
Anything slackware based has run fine for me and it doesn't take me more than a minute to get them configured for what I need.
Wifislax is a spanish kali ripoff but it has some good packages pre-installed. It has some cracking software that comes with it so I play with that once in a while.
Porteus is comfy good for if I need to carry around something to just browse the net with.
Puppylinux is bread and butter basic recovery of something that is probably on its last leg.
What about TENS aka LPS?
en.wikipedia.org
it has no browser
it used to be xubuntu.. i wonder how many people got fucked by that.
I just use whatever I have at the time.
I too also like not having any packages.

Knoppix
Used to be ubuntu, now it's void. The ubuntu installer being broken beyond any repair, while xbps being really good and manual installs of void actually working as intended, it makes for a better repair environment.
