On my third MacBook Pro, and I've had it since 2010, it was dropped once off a bed onto the carpet floor, thankfully not a scratch.
And she still ticks along, I maxed it out at the time I bought it bar the memory, I can't remember if they offered SSD drives back then? Anyway it now has 8GB Crucial RAM and a Samsung 512Gb SSD. It runs fine but I do think Yosemite has slowed it down in a couple of areas?
Anyway, my Mac laptop has outlasted tons of people I know with PC's.. I even upgraded my brother in laws old iMac the other month, I think it's a 2008 model, maxed the RAM out and fitted a 3 terabyte hybrid SSD / HDD drive. He said it runs great!
It is stunning value, I like it when you spend that bit extra but you get something that lasts.
I will buy a new one someday, so long as it can run Crysis one in parallels I'll be happy. And run a nice 24" 4K monitor for other tasks.
