Even if this is real, and not image editing, would you really want to do much with a Revit model on a phone-sized screen? I would also assume that Revit is not running on the phone, but that the application is running on a remote computer and the phone screen is just a remote viewer. Given my experience trying to do this connecting over the Internet from my home computer to a virtual machine at work, which worked but was slow and rather exasperating, I cannot imagine the experience would be better on a tiny screen and only a touch interface.
But I am willing to be proved wrong. 🙂
