It's weird though, why would I want to read on laptop? I can use a kindle, phone, ipad!

Programming books? Comics in CBR, CBZ format? Not everyone has a full set of screens (reader, phone, pad, laptop, desktop).

wonder if this warrants a [dupe] though. Different article, different thoughts, different authors.

Nice suggestions, thanks

Atom and Markdown. You can even see real time previews with "Markdown preview plus" plugin, upload it to git if need be.
