Ok...the wife wants a steampunk style build for her computer now. I looked around and she is dead set on the old typewriter style. My question is this....I am looking for a LONG term bulletproof keyboard that will last her for the rest of her life. Should I be looking at mechanical keyboards? or what style? Hoping for waterproof, but moddable, and able to make billions of keystrokes. or am I just looking at purchasing about 4 of the keyboards for replacement parts/swap out?
