I'm stuck between 1, 5 and 7.
1: It's old but sounds like it's functional. Could download some old DOS games and play that. Could maybe even do some coding if I can find a compiler that will run in win95. though this type of speed is essentially what we have at work, and I want to pull my hair out all the time when I try to do anything because it's so slow. Everything is about waiting. Open a folder, wait. Open an excel doc, definitely wait. It can be frustrating. Though, it would perhaps make that year go by faster as I would eventually get used to the slowness.
5: lack of mouse would be annoying for a GUI OS like windows, but I can find key board based games, or code, etc. 1, being slower in hardware would still be faster to operate though because I'm not dicking around trying to select stuff with the keyboard
7: I could live with the language, but the keyboard layout is kinda a killer, but if the layout is always the same I could try to learn it and eventually be as good with it as I am with querty. First step would be to try to download a typing program and basically start over like when I first learned keyboarding.
I think I would end up going with 1.
