When I got my mbp last friday I noticed the yellowing screen issue soon after starting. There was also the fact that the screen didnt shut flesh with the base. I was actually going to ignore both of those problems but now my screen is completely messed up as it seems to have a wierd effect, kind of like being stuck in the infrared camera effect from photobooth all the time. This is very disheartening and I will be bringing it to the genious bar tomorrow. My first major dissappointment with an apple product comes on a $3k machine
