sup thinksisters

What do you think would b a good thinkpad to act as a language learning companion notebook more or less stationary on its own desk? Obviously some shit spec model to minimize distractions but I'm not sure which have the best keyboard options available from third parties (japanese) or less eye-fatiguing screens.

Honestly looking at an x230 but maybe that'll lead to more tinkering than using and I should go even older for something with a 4:3 screen (X/T61)? Maybe bigger is better (W530)?
