I started using MacBooks when they switched to Intel around 2008. Maybe this is a sign to move on. Currently using a mid 2014 model, I like the slim form factor, but I don't like the absence of an ethernet port. I don't care much for the retina display, my 2008 matte model was better. Been looking at the Lenovo T470. I need something that would be easy to replace quickly anywhere in the world. What should I get?
Lenovo Thinkpad laptops are pretty good, and in my experience run Linux very well. Get something with AMD APU (there should be new models coming out soon with Zen 2 + Vega).
The only annoyance is their refusal to refund Windows tax. But now Lenovo partnered with RedHat/IBM and started selling some laptops with Linux pre-installed (Fedora), so you can avoid Windows tax there, even if you don't plan to use Fedora. I hope that will eventually extend to all their models.
