This looks cool. Looking forward to give it a try.
For years I've been using Deckset[0] for all my presentations. Being able to just edit a text file to write and update slides is a massive advantage. I usually export them as pdf, which 99% of conferences are happy with.
A big bonus is that you can now version control your slides, allow them to get forked, etc.
If you're curious to see what those slides look like, check any of my previous talks [1].
