I love my 12 inch macbook, and would highly recommend it to anyone who travels a lot. Single USB-C can be a deal breaker if you plug things into your laptop a lot, but I'm not in that camp (in fact I just airdrop things via my phone 99% of the time). Battery life is good, it's snappy, and the screen is gorgeous. I can go into more detail upon request.
Edit: buy refurb if you're interested. I picked up the highest spec macbook from Macworld for sub $1250 (the starting price of the base model), and it came minty-fresh. If I remember correctly, there wasn't even tax!
