I had my appointment today with the geniuses at the apple store. I explained my issues and surprisingly he didnt even bother to check the unit. He went to talk with his manager and when he came back he had a new unit in his hands. I was more than happy to have the unit replaced. Im happy to report that this unit has no connection problems at all. I've been running the unit connected wirelessly to the internet and havent have a single dropout so far.
Ps. WOW The macbook gets HOT when watching youtube videos (arount 60-65 C) I thought it was a problem with the other unit but this one runs hot as well when watching youtube videos.
