i harbour plans to set up a cpm system for home use. for an offline never connected to the web system. any rasp pi will at some point be connected no matter how barebones i make it. for updates, for convenience. with cpm there'll be far less incentive to do so.

a decent text editor, a spreadsheet, a basic compiler, maybe a small database. nothing fancy. distraction free, no worries about security, just 1 cpu and a limited amount of ram and storage working for me and me alone.
