I have been trying the new Inbox by Gmail, and it's somewhat useful IMO. It bundles your email into groups, just like the Social and Promotions tabs in Gmail. You can then mark things as "done" if you would normally mark it read and archive it. I am an old school webmail kinda guy, so I resisted the change at first, but I can see how it might actually be useful.
You can also use the traditional Gmail interface along with it, if you want to switch back and forth. So you're not committed to the change if you don't like it (yet).
I have a few invites if others are interested. Just ask here in the thread. A FEW ONLY.
