It still strikes me how Google Apps users, who actually pay for GMail & Co., are always the last ones to get the new stuff.
I truly don't get the delay on both Inbox and Now - are the backend Gmail systems completely different? If it's just a worry that "enterprise won't like it," why not allow it to be turned on/off from the Admin console like so many other things?
I'd feel a lot better if they'd just explain what the hold up was, or if they don't plan on expanding to Apps customers. I'd be disappointed but at least I wouldn't be completely in the dark.
They test new ideas and features on the luxury brands and then roll them out to the mass market brands later at lower prices.
