I keep hearing about this supposed terrible thinkpad quality. Can you expand on that? I purchased one in December 2012 and I think the build quality is excellent. They did change the keyboard, but not everyone hates it (I think it's just fine and still embodies the spirit/feel of the old keyboards).
