Took delivery of my Core i7 iMac on Friday and it's a fine machine, gorgeous display, fast as lightening, no dead pixels etc. etc. However, being an avid reader of this forum kind of damages my enjoyment of my new toy as reading every thread makes you sort of paranoid that your machine may not be correct. For instance the HD noise "issue".....well yep, I can hear my HD but is it in-correct? Would I have even questioned it if I hadn't read the threads regarding apparent HD noise? Now we have the yellow tinge screen "issue" - same thing applies as the HD. Don't get me wrong, I'm as guilty as the next Macrumours forum poster in contributing to this critical phenomena and this is an open forum which is a truly valuable resource. However sometimes I wonder if by reading these threads (and once you see a thread title you just have to read it) I allow myself to detect faults that might not really be there or that I would usually consider a non issue. Anyway, for the time being I'm loving this iMac.
