My old 15" MBP (Snow Leopard) was a bit heavier and thicker, but I was never afraid to carry it around one handed. But with the new thinner model (just released version on Maverick), I've heard some noises that give me pause. It sounds like something might snap when I pick it up one-handed on the right side (the balance point is over the SD Card slot). Anyone else noticing how fragile the new frame seems to be? Anyone have problems with the frame cracking or breaking due to this?
