Great potential, but falls short of expectations for business use

Stunning usability and user friendliness, awesome animations, but...
- poor quality of exported files (only PDF export works decently). Limited compatibility with Powerpoint and even Mac Keynote
-animations are lovely, but can only be seen on an iPad
-crashes regularly in Presenter mode. I wouldnt trust it while giving an important business presentation
-Polish diacritic fonts look terrible
-you cannot import new fonts, e.g. Your compulsory corporate font

So, if you want to use it to make holiday photo slideshow for your friends and family, get it now. But if you are willing to use it for business needs instead of Powerpoint -forget it and wait for a new, improved version. After the flaws are removed, it will be the best presentation app Ive ever seen.
