Laptop model: Thinkpad T440p CPU: Intel® Core™ i7-4710MQ CPU @ 2.50GHz × 8 RAM: 12GB Screen: 14" Matte Personal comments: Debian works well. Wish I upgraded the screen. Battery life is meh ~4hrs and drains while sleeping. Bit thick and takes a lot of space in backpack. Intermittently, the fan will sound like it's hitting something and make a terrible whirring noise. Gets taken care of by a few spurts of compressed air. Used as my 'desktop' at home. --- Laptop model: Mackbook Pro 2015 CPU: i5 - 2.7ghz RAM: 8GB Screen: 13" Personal comments: Decent battery life and works well for travel. Good keyboard like T440p. Not a fan of the OS but hardware-wise works very well. Used as my personal travel laptop. --- Laptop model: Mackbook Pro 2018 CPU: i7? RAM: 16GB Screen: 15" Personal comments: Very good battery life. 15" is bigger than I'm used to, but I've started to appreciate the screen real estate without external monitor. Probably my least favorite laptop to use simply because the keys consistently double tap and I can't feel for fn keys (fn, volume, brightness). Work-provided laptop. In summary, I'd lean towards a Thinkpad carbon for the ideal combination of portability, keyboard, and ability to run Linux. Never appreciated quality screens until using Macs - will definitely be upgrading future laptop screens.
