I really like Deckset. I've been using it regularly since May 2014 when it was first released and since then I have used it to prepare 29 technical presentations, the latest just this morning. I find it helps me focus on content and less on formatting. I *enjoy* preparing presentations with Deckset. I still revert to Keynote for the very few presentations when I absolutely must have complete control over formatting - for example, if I need to annotate figures or plots, or squish several figures together, etc. etc. (I have also sometimes done this sort of thing in Keynote, exported the result as PDF, and then used that inside Deckset.) Like the previous reviewer, it has made me revisit my approach to designing presentations, and the fact that one can simply switch between its impressive themes at any point makes it easy to test which fulfils the purpose of the presentation best. (I tend to favor simple themes with either a white or black background - they tend to work best for technical presentations.) My one significant quibble - that I sometimes just absolutely need to reduce a font size to fit something on one slide - has been removed in the current release, which allows autoscaling of slide content to make it fit. A really nice program.
