I agree!
The Amiga notion is "Because We Can" and I think the fun comes from
getting a 7Mhz machine with 2mb RAM online!
I mean, it would be better to minimise GUI usage and just use text
based things but it can be done.
An Amiga with Workbench will always be more versatile and resource
efficient compared to an equivalent Windows or MacOS
environment, and more practical and productive than Linux.
Although for older machines especially PCs, I've heard that Slackware
is worth playing with.
:-D
