Blogs have been abuzz with indications of google launching their online presentation tool soon. Not something which would have taken their competitors by surprise. The way they have been launching products, buying companies and hiring people shows that they indent to have a strong presence here.
Apart from a presentation tool and wiki, I hope they would come up with an online cabinet system for maintaining such files similar to what is already provided by jot. Moreover, they need to plug in some key features into their spreadsheet and docs to make them handy. Not allowing graphs in their spreadsheets irk me a lot. Their were small issues as well with copy-pasting jobs also the last time I checked it.
