I had an instance a few years ago where I had to use an emergency/backup computer that I couldn't network in any way (
very old laptop (AMD K6-2 :D) that only had a USB port, my modem's Wi-Fi was broken and I had no USB Ethernet adapters).
And... using that thing was really really nice. Getting data into it was enough of a small chore that it was remarkably focusing.
At one point, the only bootable CDs for i586 in the house were a couple old half-scratched Slackware discs. A lot of things refused to install, but sed did... um.
I can't remember why but I ended up reinstalling quite a bit (I think from "no I don't like this partition table layout") and so I wanted a simple package selector/installer. So I tried writing one using bash and way, way too many regular expressions. I started getting a (literal) headache after staring at screenfuls of modem line noise for about a week and had to give up. But I know how to left- and right-justify text using sed now (and I frequently use sed's full command set), which is kind of cool.
It's quite sad that our brains are so easy to distract with "and through this door we have A PURE STREAM OF ALL THE WORLD'S INFORMATION". It's sad because we live in a hyper-connected age, and yet we just can't mentally scale to cope with it.
