I feel like dyesubs are kind of wasted on rounded sans serif typefaces that look just like what you could produce as double-shots, or on boring Helvetica that looks like it comes directly from some corporate committee.
Why don’t we have any serifs on keycap legends? E.g.

(This is just a concept; would still need a lot of tweaking.)
Keep it Upper Case because it's easily recognized from a distance what each letter is. Makes it easier for 'Microsoft Windows' to select his type so easily with this font.
We should look at acquiring an all Serif Typeface for our keyboards because I think this could be the FIRST key-set, that should be sent to SP for manufacture.
