i have a mid-2015. i just like it. aluminum body, good screen, i don't mind the keyboard, the trackpad is fantastic. I really want a physical escape key. I've thought about, and can readily afford, a newer model. the 32g memory would be nice.
It has been a long time since i felt like i need to start searching for a linux capable laptop. i've felt like that for a long while though. i consciously know it's not that hard to find quality hardware. I still have some subconscious apprehension. Trying to find a pcmcia network card to work with my thinkpad was such a pain back in the day. i have not so fond memories of trying to compile tulip.c into a kernel module.
MacOS was a breath of fresh air. everything just worked, and i had a real unix to work with. darwin isn't the greatest thing ever, but the hardware was nice. The air is getting kinda stale though. i need to find some hardware and make it right. the apple heyday made me complacent.
