....so I'm becoming the Obsessive Compulsive Mac buyer, it seems. I'm afraid the genius won't see it as an issue.
Uh huh.
Lots of MBPs have slightly uneven lids. It's not necessarily the build process itself that's wrong. The problem is that the aluminium bent a bit. Sometimes they just straighten out on their own after awhile.
Plastic Macs have rarely had a problem because the plastic used is stiff.
Cost isn't even the issue. It doesn't matter if you paid $10 or $20,000. The lid should close properly.
It does. There's just a tiny gap. Again, it may straighten itself out as you continue to use it.
When I first switched to Macs after a lifetime of PC use, I was amazed by the build quality. I have had Dells, Toshibas, E-Machines, and an assortment of other laptops. All of them have broken in under two years. I purchased a mid-2007 MBP and have had no issues whatsoever. I thought that trend would continue when I got my MBA, but it didn't. I'm not sure what happened in that small amount of time, but it seems Apple has been slacking on QC.
So you've only had 2 other Macs before this one? Since when was buying one Mac in perfect condition considered a "trend"? Apparently, now you've had 1 perfect Mac, and 1 with initial flaws, and 1 that's only 99% perfect.
I don't know if Apple's QC has been lacking. According to the Apple store I went to to get my MB fixed last week, the new unibody MBs and MBPs have had much fewer problems than ever. I asked them about it because my plastic MacBook has had quite a few issues, some of them nagging issues, but some serious ones in the past.
