I got an invite to use Google's new Inbox thingy the other day.  If you haven't seen it, it's a layer over Gmail that bundles messages into thematic groups and lets you deal with them in large batches.

It's an interesting notion, though it doesn't exactly match the way I've been using Gmail (which is to use the Priority Inbox, and strive to keep "Important and Unread" clear while letting stuff accumulate in the rest of the Inbox).  Still, that's something that could be managed over time.

The showstopper I encountered was when actually composing a message.  It doesn't include the per-sender-address signatures defined in Gmail.  I waited literally years​ for Google to add that feature, I'm not going to give it up now.

Ugh, I hadn't noticed (I only use signatures these days on my work account, and I use the same one there regardless.)

Leave feedback! I'm definitely pointing out missing things as I go -- for example, I couldn't mail to a a contacts group. Very bad; I had to pull up Gmail to send mail and it's going to happen on a regular basis. I left feedback. There was something else, but it slips my mind at the moment.

Generally, though, it fits my use patterns pretty well. I can certainly see it won't for others. I love the snooze feature with a great love, though; much like "don't show this to me until X" in todo list managers, which has become an essential feature to me (and my sanity.)

Ultimately I think it's for people who're already using their inbox as a todo list, which I do.
Oh, I left feedback. :) I also left feedback about the fact that Inbox doesn't have the spambox-clearing functions that regular Gmail does. I'll keep an eye on it.
Ah yes, that was the other thing -- I sent feedback about how it's a pill to check spam for false positives. I need to send them another one about how the formatting in compose doesn't include fonts, specifically the ability to change a section to non-proportional. I was sending a technical email, you know, and...
