I have an otaku keyboard. It can be a little tricky on passwords, but it isn't that bad. The amusing thing is, even blank, looking at the keys can help. Aside from my work laptop, I can always type pw in notepad first, then just to be sure that I got it right, copy and paste from there. In the case of my laptop, I could always raise the lid, if I was on my third try, or connect a back up board, but so far that hasn't been necessary. I thought about printing out a legend on paper for reference, but really, the only things I forget what they are is print screen/sys req, scroll lock and pause/break.
