Powerpoint /Open Office Templates

I have been continuing my research on presentation tools in Powerpoint or Open Office. I haven't found any other real differences between the two of them except for the links within the document. I did find a nice site that has a lot of different templates. A lot of the templates are in .ppt format (Powerpoint) or .odp format (Open Office Impress). I really recommend that if you are looking for a place to start - Presentation Helper for Open Office or use any of these powerpoint templates, which will open in either Microsoft Office or Open Office. I really recommend that you spend some time looking at the entire site.
