I've seen several threads on this but I don't see the solution I'm looking for: I use Powerpoint (PC) and Keynote on my iPad for sales presentations. The problem - corporate rules dictate we refrain from altering approved presentation material for several reasons but most of all to maintain brand integrity. When I send PPT presentations to myself - open them up in Keynote - the problematic formatting renders the presentation unusable for customer facing presentations. At the very least, I would like to be able to globally reformat the fonts to fit the presentation screen on my iPad. Is there a rapid way to perform this function - or must I take the tedious steps of reformatting the slides individually?
