MacBook...
Well, I just received a new MacBook as a replacement of another one with two little 'grains' in the trackpad that were not noticeable, unless you were looking for them, but were very annoying when using the trackpad. It was like if my finger had something, or like if there were some salt or sand on the trackpad. Anyhow, it got replaced and the new one also has the grain, although it is just one. When looking at it closely, it looks like a little bit of metal or someting just coming out in the middle of the trackpad. That is why it is annoying, since it is the are most commonly used. Anyow, I though I was the only one with this but found this tread. Could you please describe your 'buble' just to see if we are talking about the same thing?
Thanks
