I have a 2016 m5, I travel frequently (I mean, a lot) and often commute around Europe for work, and I wanted a portable laptop I could easily put into my hand luggage (often I just travel with hand luggage alone when flying) but something that was powerful enough to do some photo editing, as well as basic stuff like Office and web browsing.
The MacBook is absolutely perfect. It allows me to keep in touch wherever I am, and I just carry the small charger and the Apple USB-C adapter (the one with USB-A, USB-C and an HDMI out) which meets all my connectivity needs.
It's perfectly capable of streaming HD video from the likes of Netflix and Amazon (well useful when you are a frequent traveller) as well.
Yes it isn't the most powerful laptop in the world, but I don't care, the form factor is brilliant, it is incredibly lightweight and does everything I need.
I love it!
