Thanks for your feedback, David.

The comparison with Excel always comes up first. I'm not trying to suddenly move people from using Excel. I'm making something which does what Excel cannot do well or easily. I guess I need to make this message clear on my site.

Pretty Graph has a PDF download feature which addresses the presentation issue. I can also add copy saying that you can use the images also in Powerpoint. I am also looking to add a direct export to PPT feature.

I had a quick look at oomfo. It looks nice, but it's not web-based and although I'm not saying desktop apps are no good, I've chosen the online space.

Other planned features, which should hopefully be useful (and "viral") are easy sharing and collaborating on graphs.
