No, the screen resolutions is a serious problem. Design your slides on a big desktop, and half the slide will be invisible on iPad. This is a problem with projectors, where I have given talks from 640x480 to 1024x768 and beyond. What size do I design my slides at? Why bother converting a powerpoint presentation? Is this really that much better than putting a PDF on your website?
