Powerpoint Presentation slideshow in gmail

You can now view powerpoint presentations attached with your gmail messages as slideshow. See the 'View as Slideshow' option in gmail image below :

Previously you could open Word and Excel files in Google Docs and Spreadsheets and they have supported Powerpoint files too which is another step towards strengthening online offering of office applications by google. Although you can't edit these powerpoint files for now like you can do with word & excel files in Google Docs & spreadsheet but google application team is working on a presentation application which will let you edit powerpoint files & create presentations from scratch.
