Surfaces are great devices. My Pro 3 still gets 7 hours of battery life.

We use newer Surface laptops at work, even the artists, developers, and executives (note we are not a tech company). The laptops aren't very fast but they can take a lot of physical abuse and the batteries last all day. We don't need the top of the line, and forcing our developers to use lower powered computers actually improves the quality of the apps because they get to experience how our apps work for most of our customers and take performance into account from the beginning.
