I still have my MBP which I got in June of this year. It's still running great and I'm still loving Mac OSX over Windows by miles, Windows feels very "messy" compared to Mac OSX. Anyway, I have noticed on the back of my Macbook Pro, if I tilt it to the light of a window (let's say) I can see 2 lines an inch apart running from the battery area up to the rubber/exhaust area of my Macbook Pro. These have obviously been caused by heat. Is this anything to worry about? Secondly, more worrying is the fact that my Macbook Pro has a "bend" above the battery area, above the ram cover that can be felt and seen. Is this a worrying matter and does anyone else have this? Lastly, I have noticed when I close my Macbook Pro's lid that it doesn't sit flush it bends up slightly into a very wide "U". Anyone else have this? I don't have a camera at present so it is hard to explain but hopefully you know what I mean and it is nothing to worry about. Your thoughts would be great. Thanks .
