I have the magic keyboard, which doubles as a case. It's actually a pretty decent keyboard, though it certainly adds to the weight of the device. Pretty easy to recommend though.

I have the apple pencil and it works pretty well for drawing, but I don't otherwise use it for anything else.

I don't really have anything else accessory wise :).

This is so funny to me and will never understand the logic in buying a more expensive stripped down laptop, then spending MORE money to upgrade it back into a laptop? Take away all the ports, then just buy a dock to add the ports back. Take away the keyboad and mouse, no problem, just buy a wireless trackpad and keyboard! Oh, speakers suck cause they are too small, just get out bluetooth speakers! They are made by Dr. Dre!!!

Are we just showing off how much money we can waste at this point?
