So I had a 2010 Macbook Pro and I didn't notice any flex at all whatsoever, however, I bought a 2011 Macbook Pro a couple months back and I'm starting to notice some. It's around the top cover, basically if you press down against the lid it flexes some. I understand the screen is directly beneath the lid and I don't know if it should be 100% rigid or not. If it matters, I opened my Macbook Pro (back when I first got it) to install RAM and an HDD. Does anyone else notice some flex around their lid?
