Well, if you're looking for battery life, both safari and edge have excellent battery life by virtue of not doing anything useful.

And if you're looking to do dev work, that usually means at minimum an editor, a server, and a browser, which seems like too much to run unplugged.

Unless your editor is actually a webapp itself, I don't see how that's going to tip anything over the edge in terms of practicality...

The resources consumed by any web server I can think of are entirely inconsequential.
