Paste was recently released at version 2.0, and if you are looking for a way to differentiate your presentation deck, be sure to check it out. You can create an account from your Google login and create up to 3 decks on the free plan.
There are some really cool ideas, such as collaborating on the decks with reactions and reflowing the content on a screen as you resize objects.
The decks can be shared, embedded, or downloaded as a PDF version. I wish they had a cheaper education version.
