Single UI for Google+, Contacts and Calendar (unofficial)

Google hasn't released or announced anything yet but the presentation seems legit and the uploader identifies himself as Vladimir Dolgov - head of Google Russia[1].

I'm not a big fan of the Google+ UI, but it's simple and I've always wanted Google to better integrate (or merge) all their products into a single Web application - à la Facebook. In the end, they might have to manage only one design and provide one search box for all public[2], social[3] and personal searches (à la Greplin[4]).

Don't really like the Google+ UI... I guess its ok till its contacts and calender... but changing the Gmail UI would be really a suicide.
