I've been following them for only a few months, sure, but I've seen that link and others, and watched many of their videos. It's extremely concerning that they use a stylus, they clearly don't have multitouch support, copy/paste is based on a control key, screen tearing is significant and some of the UIs aren't scaled properly, I haven't seen them do text selection and the keyboard didn't give feedback. That's just a few issues.

Also, the videos are legit for the software, but they are all running on the Dev Kit, not the actual phone hardware, which we haven't seen and have no idea what the progress on is like. So the hardware kinda does look like vaporware. In the link you have, for instance, the best they can do is take a fake circuit board image and fade it into a fake phone image. That's not encouraging.
