Google Launches Powerpoint Preview for Gmail
Google has launched Powerpoint Preview for Gmail.
Gmail users can use Google’s Powerpoint competitor through a View as Slideshow feature.

When you receive an email with a Powerpoint attached, you can view the slideshow in a new window – no need to download and open in Powerpoint itself.
Gmail already provides options for opening Word and Excel files in Google Docs and Spreadsheets.
