I really like the aesthetics but as mentioned here it's not portable / shareable offline.
In addition - more than the fact that you need a modern browser (which is ok, really), you need a modern projector for such a resolution, and this is nothing you can just download and install.
Nothing is more awkward than displaying such a presentation on a backwards projector which cuts it off.
I use this regularily, which solves both problems: https://github.com/geraldb/slideshow
I plan to use this from now on, since it has nicer UI: https://github.com/juliocesar/shining
For deck.js to be perfect it
- needs to understand markdown
- needs to use precent (%) scaling so it could scale resolutions easily
- export to an offline format.
All in all it has astonishing UI effects which makes me want to use it.
