For travel, I prefer matte screens (glare really affects me, causing headaches as I try to focus around reflected windows and lights, and especially reflected motion from myself and the environment), good keyboards and even lighter laptops: while ~300gr of difference between a Thinkpad X1 Carbon and MBP14 is not much, it adds up in your bag. It's got a full day of battery too, though more is always better :)

Not to mention soft-touch rubbery palmrest: I hope they never move away from that, it's perfect (though I don't care about it being a fingerprint magnet, which it is).
