Let me get this out of the way. The replacement MBP I got is significantly better than the first one I bought. The first one had what appeared to be a dead pixel just off center of screen, uneven keyboard backlighting - at max brightness the 5 key shined like a star but the others were dim, and abnormal heat. The one I swapped with is more even on the keyboard, no dead pixels, and is just as cool as my 2010 - iStat Pro would report idles of 40 degrees Celsius on first one, 31 degrees Celsius on the replacement. So obviously there is a bad batch of them out there, cause this one is damn near perfect. Haven't hammered it with anything yet - I will be doing some Adobe Premiere encoding this morning as I have to catch up on my video reviews, so I'll report back then. In any event, if you're having issues with your backlighting being uneven, dead pixels, or anything else abnormal, RETURN IT and exchange it. You might actually get a good one. But I wanted to report my Genius Bar experience too as it's my first time ever having to use them for anything. Never had any problem with an Apple product before. So I go in there and the guy asks what's wrong. I bring out the MBP, show him the pixel on screen. At first he thinks it's dust on the screen, like I did, but then when I show him how it disappears at different angles and isn't visible when you view black colors he agreed it was a pixel problem. I then pointed out the keyboard backlighting being so uneven; he didn't see it at first, then when I used the screen to darken the area he saw what was going on, and we saw the display model was more even, so he agreed there as well. Didn't mention the heat as I felt it was to be expected with this much authority in the thing. So he says he'll just swap me out, I'm like cool. Brings out the replacement and asks me to check it out. While I'm doing so he casually asks me if I work for a large company. This initially irritated me since I was wearing my company shirt, but I let it slide and pointed out the logo to him. He looked it up and saw that my company indeed gets 8% off Apple computers, offers to basically swap me and credit back the difference since they never offered me the corporate discount the first time I shopped, and I never thought to ask as the website gives a terrible - I mean TERRIBLE - discount for employees...like $90 off of a $2000 machine or something. Seems the local store gives a steeper discount than what our company tells us. I was surprised that this guy was going above and beyond by telling me this. But then I got angry, since I've bought 5 other computers over the past two years and NOT ONCE told that there might be a company discount. Wasn't his fault, but it really bugged me. Would have REALLY helped with the iMac in particular. So anyway, I have now a 17" that is worth the money I paid for it, $220 is back in my wallet that should never have left it, and I actually had a very positive experience with Apple's Genius Bar. I had initially hesitated on taking it back and just dealing with the issues, but I knew that if I didn't do it today, I'd never make time. I'm glad I actually did.
