"The issue you have with HTML versus powerpoint means you're doing it wrong in the first place, not that HTML is the issue."
I take exception to this, you see I believe in making something clean, simple and *precise*. If I have an image being rendered somewhere, I want it to render there and ONLY there, and I want it to be precisely positioned.
Perhaps you don't care about the layout of your work, but I do. And just because I do, doesn't mean that I spend more time on the look of a presentation than on its content. In fact, I'd rather NOT spend forever and a day making sure my presentation looks right, which is exactly why I'd choose PowerPoint over making a website, because I don't HAVE to test it at different resolutions on different browsers to make sure it'll function correctly, I can design it once and be done with it! I'm not arguing that PowerPoint isn't capable of funnelling the user into some God awful design choices regarding their presentation layout and its information, but it sure as shit is faster at creating something visually accurate than building a site in html5. That is, unless you want to do something beyond the (admittedly strict) limits of PowerPoint such as complex animation. But then you'd be spending more time on the visual look than on the content itself, which you seem to be against.
