And personally, I think that we passed the point of adequate specs for most purposes 8 years ago. I have two MBPs. One is a 2008 that is beat to hell at this point but still functions pretty darn well with an SSD and maxed out RAM. It's good enough I've been able to do most day-to-day development with it and audio production up through this summer. If it were effectively invulnerable and weren't eventually going to stop receiving OS updates (or if security/compatibility weren't a concern), I could conceive of using it indefinitely for most work. I also have a 2012 that is still adequate (though, weirdly, sometimes worse in terms of locking up, not sure if that's the later version of OS X or no SSD). I bought it not because I needed anything newer, but because I didn't want to be stuck searching for a replacement when the 2008 fails. And perhaps interestingly, I bought it used because Apple has decided to no longer offer a 15" model with a matte screen that's upgradable anymore.
