im new around here. ive been lurking for a few weeks reading all the post about problems with the iMacs. this morning i finally went and got my first mac. its a 21.5 inch base model iMac. i was a little worried about the noisy HD and maybe the yellowish coloring on the screen. i really wanted it so i just went for it. it seems to be perfect. it doesnt seem to have any flaws even tho i keep finding myself looking for the yellowish tint. LOL. but it looks good. i checked and its a week 4 build which im assuming is this week or last week. but its great. runs good and im happy.
