If you're anything like us, Google's Gmail has an iron grip on your life. Google's looking to create a whole new iron grip with a new app from its Gmail team, and it's called "Inbox." What is it? That's a good question -- Google's made a demo slash advertisement video that we've dropped below. As far as we can tell, Inbox is a combination of Google Now and your Gmail inbox -- a "smart" inbox, if you will. It combines alike pieces of email (bank invoices, for example), highlights related information (like Google Now alerting you to flight changes, traffic, etc.) and keeps track of your life (it'll give you reminders, among other heads ups). Is this the end of Gmail? We seriously doubt it, but it is Google's latest foray into simplifying email. Head below for more!
