As an avid Keynote user on the Mac, like others I was excited to have Keynote for the iPad. But there seems to be problems with font substitutions, lack of availability of our Master slides and loads of other problems. Sounds like you need to use standard fonts (i.e. those available on iPad – this excludes the use of Myriad which is Apple’s corporate font), and edit all your slides on the Mac (NOT the iPad or you’ll end up with messed up slides). Speakers notes appear to disappear too.
This is a real shame because lots of us want to edit and add slides on the iPad and reopen the files on the Mac with no corruption of our hard work!
Yet another reason for holding on to that MacBook! The iPad cannot totally replace your Mac.
