I usually have a very hard time switching from my mac computers keyboards to any other PC, I don't know why it may just be me, but I type poorly when I get on a pc. This keyboard is great though! I love the backlight which it dimmable and the keys are spaced well and feel good to the touch in response speed and a solid "click" of sorts. The physical texture feels nice too, almost a smooth soft rubbery texture, but no sloppy play (if that makes sense to anyone or is an issue haha). The trackpad is sensitive and responsive, jet I hit it with my thumb a lot while typing papers for school and my curser jumps all over the page. I recently turned the delay in the track pad up in the settings and this has helped a great deal. Sometimes I do have some issues clicking, it could be the trackpad of the compter, system, app, etc, idk. Overall not a big issue. The function/hotkeys area just ok, the F1 and F2 keys only adjust the keyboard backlighting, not the screen brightness which is holding the Fn key and tapping the Del or Backspace keys to adjust screen brightness. This seems odd to me as I think screen brightness woud be more important than the keyboard. The magnetic lock to the computer is strong and secure, and the raise up mode works just as well. To take notes with the pen I pull the keyboard off and connect it on backwards and it makes a nice surface to rest my computer on the write.Theres no sag in the keyboard when up in the angled position and no bounce either, which were concerns I had. Also the cover has stayed clean although I am still nerveous about that and how to clean it. Not much else to say other than if you get a S.P. I would highly recommend sucking it up and paying the extra cash for the keyboard, the one in the screen itself wouldn't be worthy of any substantial or expedient typing. I have heard of connectivity problems with the computer (not recognizing the type cover) I had the same problem at first, it goes away once your computer is finally up to date, which takes a week or so. PS: make sure you get the keyboard for the surface pro 4, I hear the older models aren't nearly as nice.
