This is probably a pretty useless post on this forum (everyone knows they rock), but I kind of want to say what I currently feel. I'm typing this post using a rubber dome keyboard, that's what made me want to post this in the first place!
So I bought a mechanical keyboard for personal use somewhere last year (a Filco).
Then the beginning of this year, I bought a second one (myself) for using it at my work.
So for the last three months or so I have never used anything else than mechanical keyboards.
Now due to being somewhere else I've got a rubber dome keyboard in front of me, and it seems as if I've unlearned typing on one. It requires a lot more pressure. My fingers become kind of tired from typing and sometimes I accidently skip letters due to not pressing the keys deep enough. They need to be pressed all the way down into this mushy rubber.
And that while it's a logitech keyboard, logitech being a brand I once found pretty nice.
And really, my hands are feeling tired from this!
So yeah, mechanical keyboards really rock, it's not some kind of fad.
