The latest cool presentation app

I saw this Tweet by Garr Reynolds (Presentation Zen):

Great presentations are NOT achieved simply by using the latest cool app, no matter what marketers say. pic.twitter.com/A4blPpCvov

I agree fully, and as the CEO of an aspiring presentation app (SlideMagic), I am not contradicting myself. SlideMagic is of course cool, but not because it adds spectacular features. It makes you design slides in a very strict grid so that your slides look good regardless of your design experience. Try it yourself.
