Once you open an email, you can take quick action on the message using the menu button. Your standard Reply, Reply All, Forward, Mark Unread, and Delete are all just a click away. This makes handling your email easy and fast. I can browse my email and scan for spam, then quickly nuke it. This way, when I get to my o ce I have few spam mails left, and less work to get to the heart of my inbox.
