I received my i7 and after reading all the posts here about: 1) flickering 2) grumbling 3) specks of dust 4) backlight problems 5) dead pixels 6) etc., etc., etc. I have decided to just give up looking for problems and just start enjoying the machine for what it is - a really nice looking computer. Seriously, I know I am a bit OCD but this was just getting to point of being ludicrous. So to all others in the same boat, I wish you well. Hopefully I can get on with my life now.
