Other than the heat issue which can be fixed to not really be a bother for me what are other issues of the 1.83mbp. I did a search but the heat issue is the only one comming up. A certain Apple store in the Los Angeles/O.C. area is offering an open box MBP for $1459 while all the others are offering the same comp and same specs at $1699. Any one know a reason for the discrepency also? Thank you.
