I just got a new Logitech K840 Mechanical Keyboard because I noticed some of the keys were sticking on my old Microsoft one. Granted it was 8 years old but still worked reasonably well. So far I’m happy with this new one, it definitely feels and sounds different, sort of like the first PC keyboard I can remember. I like that! It doesn’t have Num-Lock or Scroll-Lock indicators, so that’s kind of weird, but those aren’t buttons I hit very often anyway I guess. I’ll probably post an update after I’ve used it for a while.
