Airdeck is a hidden gem just like Pubcoder.
I give it full five tacos. Here is a short review:

Multimedia presentations with a bit of interactivity built in has been proven to be much better than plain videos or simple presentations.

Pros:
1. Solid company behind Airdeck - Airdeck has raised close to 4 million in funding and thus, is well poised to develop in to a well polished presentations platform. See: https://airdeck.co/airdeck-inc-raises-750000-in-series-iii-seed-round/
2. The application is well designed and the UX/UI is well made. Regular updates (https://airdeck.co/changelog/)
3. The CEO has just indicated that the Tier III will receive white-labelling as well as CNAME.
4. The player is well-made with auto-advance.
5. Support for multiple file format imports covering every possible need. Support for embedding the presentations anywhere.
6. Analytics in Tier III can be useful to understand what the audience is interested in or paying attention to in your presentation and can be used for A/B testing too.
7. Generous limits: Unlimited decks on Tier III is great.

Limitations (for now):
1. Can't embed iframes into the presentations currently - but I believe this might change.
2. This is NOT a slides creating application. It is a presentations delivery application.
3. You can't animate any objects, text, etc in the slides: You can either add a video or an image (along with hotspots based links and surveys). However, the presentations look professional without animations.

Feature requests:
1. Ability to add additional audio or music to each slide or entire presentation
2. Slide transitions
3. Presenter View with Slide Notes - Also, a feature to add teleprompter notes that does not get recorded.
4. Ability to resize and change shape (round for eg.) of the video recording when Video+Screen recording is done. (Currently, we can move the video or make it full screen)
5. Ability to spawn a modal window with iframe contents without leaving the presentation (the modal can be maximised into a new tab)
6. Text to voice (Bring your own API model can work too)
7. Ability to add tracking codes (google analytics, facebook pixel, etc) to track conversions.
8. Add a small logo to the player as well as a watermark or logo to the videos.
9. Ability to embed google charts or such dynamic content (iframe/oembed)
10. End of presentation behaviors - Auto navigate to a landing page, Show related presentations, etc.

I highly recommend Airdeck. It is a must have in your repertoire of tools if you are a marketer, educator, coach, etc. Makes for great communications that is professional looking and involves multimedia.
