Gmail reads powerpoint files

Gmail rolled out to everyone a new feature that lets you preview PowerPoint attachments.

"Now you can open PowerPoint attachments as slideshows, without having to download anything. Just click View as slideshow next to the .ppt attachment you want to preview. Since you can open .doc and .xls attachments with Google Docs and Spreadsheets too, there's no need to leave your web browser to check out your Gmail attachments."
