On my 3rd macbook now.

1st one had discolorations on the top of the keyboard which you couldn't wipe off. Store employees used a Mr. Clean pen which didn't work, so they swapped me a new one.

2nd one had a large scratch on the upper right part of the outside, so I had that replaced as well.

3rd one is doing pretty well so far, no outside marks or dead pixels.

Some of the things I noticed while I had 3 of the different macbooks were that there are definitely differences between the panels. The 2nd one had worse negatives and worse colors on the LCD. I forget what the exact panel model was, but it was different from the 1st and 3rd which are both 9C89, and look about the same.

On the 2nd one, I could also see clearly how the manufacturing wasn't smooth on that one. Inspecting it closely, there would be close to invisible bands along the aluminum where carvings were made. Also there were nicks and spots elsewhere on the case that look like dark tiny dots. The 1st also had a couple insignificant ones on the side that didn't bother me.

Lastly, this is going to be speculative, but I feel like the smoothness of the trackpads also varies among models. The 2nd was the smoothest, the 3rd feels rough. Not sure what to make of this though, but it could be just because of moisture on my fingers. So far it doesn't feel the same.

Hope this helps.

I must be going a little nuts as well, because on this 3rd macbook, I finally just saw the thin glowing white LED bar when the macbook sleeps.. Pretty sure my 1st one did not have this because I was looking for it and thought that apple had omitted it. Not a big deal, but nice to have it back on this 3rd one.
 
2nd Macbook

I am a new Convert and have been excited about these new macbooks for a couple of months now.

I was waiting for Best Buy to get them in! Finally yesterday morning i was the first customer to get one at my local store and after drooling over it with half of the Best Buy employees who had not seen one open yet (including the Apple rep) i took it home and spent the whole day on it.

I actually LOVED it right away but later in the evening i noticed it was making a litle bit of noise. I had read up on the forums that everybody's was quiet and running smooth, so finally i just put it next to a last gen macbook, and it sounded significantly noisier. The closer i looked at it, i noticed also that the F keys were crooked and the trackpad didn't feel very tight.

So late last night I decided to take it back in the store and get it replaced. They gave me absolutely no trouble and so I just exchanged it for an identical one. Boy, am I happy i didn't just settle!!

There is a WORLD of difference in how everything feels. The keys work smoother, the trackpad feels tight and clicks more evenly across the whole surface, and more importantly the noise went away!!

So I'm assuming the whole casing was just a little loose or something like that, because the second one i got just feels much sturdier.

If you have any doubts, i encourage you to take it back just so you won't have any regrets later down the road. No manufacturing process is perfect.

Hope this is able to help somebody.
 
Closed my Macbook today on the way to an appointment. Was planning on using it on the bus. Got home a few hours later, the entire case was very hot to the touch... opened it up and the battery was nearly dead. For whatever reason the monitor went off, but I guess the computer didn't go to sleep. :mad:
