My personal theory is that the first batch of 15" AlBooks had the usual first batch issues and problems like white spots and funky latch.
Does anyone think we are past that point now, such that new PB's shipping from Apple (retail shouldn't, as the stock could be from the first batch) might be free of these problems?
A simple way to find this out, would be to track serial numbers to see if there are problems with white spots on the most recent serial numbers...
