Ugh, my dog knocked my laptop to the floor, so of course the glass cracked. It still "works" but the lifespan is not going to be long as more of the screen becomes ruined. So I need to replace the panel. I've seen a bunch of places offer the replacement for 500, apple for 700+, but you can buy the lcd itself for under 200. I've seen ifixit and it is... unclear. Anyone done it?
