Haven't been in this specific thread for a week now...since getting my new 27' imac and have to say.....I am in love. Here's hoping you all get a perfect version with no issues. As for me....I haven't came across any issues yet and this thing looks AWESOME. GREAT monitor, and quieter than a mouse in an empty house.
I got everything fully upgraded....but just the 8GB Ram...I'll be upgrading that in a month or so.
Lastly...I ordered day 1 at 6pm...and got mine over a week earlier than I was suppose to get it originally (Dec 31-Jan 7th).
Good luck all!
