I had my interview yesterday. Pretty straight forward - just asked for ID's, my passport and my EAD card and then a few questions from the I-485 form to confirm what I had written. He also asked for my medical (which he never opened). After 20 minutes he said that was all good and he would make his decision later that day after he had checked the medical and we left.
One hour later, I had an email to say my green card was being produced. Yay!
Honestly, given this has taken 2 years almost to the day, I was a little underwhelmed. There was more excitement getting my EAD and it's renewal but I am glad this is all done. I hope the process is a little faster when I come to apply for my naturalization in 3 years.
Good luck for the remainder of you out there waiting for your interviews!
