This whole thing is cracking me up. I'm writing this from my Early 2011 MBP. It just had its motherboard replaced for the GPU issue (for free) earlier this year. And it is on its 3rd HDD (last two being SSDs, the 2nd of which just got too small).
I will eventually replace it with a new MBP, even though I have a new work-provided Dell laptop sitting next to it that I haven't logged into for a few days. (It contains the older Samsung 830 originally in this MBP)
I'm simply better at my job when working from a Mac, so to me it's worth it. Nearly everyone seems to be whining about the cost of a new MBP. They've always been expensive. And people have always whined about it. Yes, I would have liked to have seen more "revolution" than "evolution" in the current MBP lineup, but honestly, I haven't heard a single negative thing about the new ones from people who actually own one. But I have heard MANY surprised reactions at how much they love them.
So yeah, maybe I'm a fanboi. But it works for me, and if I get 6 years out of a $2,500 computer, ≈$450/year ain't bad for a tool I use all day every work day.
But obviously YMMV.
