Gregory's ServerAnd then there's a ton of stuff which is kind of above and beyond - spreadsheets (Quicken), finanical software (1-2-3), scientific graphing calculator, full customizable database, full serial terminal & laplink with modem support, _scheduled tasks_! You can write cronjobs that run batch files, and it will run in the middle of the night because the thing is always on and uses no power! This is a far better, more useful DOS machine than my desktop!
I've spent the past year and a half writing DOS games on my desktop, and one thing that was consistently an annoyance is that I had no way to look at my code while my game was running. I've got a full interpreted interactive scripting language with a REPL, but I have to quit to make changes. This thing has a full text editor that I can task-switch to with a single keypress and takes up ~30kb of RAM! This could completely change my entire workflow!
