Just stop right there, OK?
Look back through my comments and you can see I've made this point a few times, but I'll make it again just for you. Mac laptops are sturdy, well made devices. My workstation provided by work is a lenovo W series laptop. I can push the bottom screen bezel and it flexes a full half inch. The plastic above the keyboard flexes also. The trackpad is meh (and TINY!). For the price (which at the time of purchase was not really inexpensive), it is cheap plastic crap.
My rMBP is solid. Feels wonderful to type on. The screen hinge stays put and doesn't shimmy. The keyboard feel solid with no flex. It's worth the price, especially compared to a lot of the junk that's out there today.
