Pretty much what I use my macbook air for - £900 back in 2013, battery still lasts several hours. The electrical tape over the webcam reduces the 'expensive looking' part.

For real work on the road I use my t410s and ubuntu (although the hinge has now gone, which is a right pain), but most of the time I do real work I'm at home and use my z440 HP workstation (also with ubuntu)

And Brew, Postgres, Atom, VIM, VirtualBox, tmux, fish and probably 100.000 more things. Why do you think Brew exists and with such stats??[1]

Do you have data to support that claim?
