If you use Gmail, have you tried their new 'Inbox' yet? If you're interested in trying it, here is an article describing the various features of Inbox. I took a look at Inbox a while back, but didn't make the switch. I like the way Gmail works for me right now, and so I'll keep using it, at least for the foreseeable future. However, if you read the article, and like what you see, perhaps you'll give Inbox a try.
