We’d be truly amazed if the iPhone 6 could actually pull this off. We don’t see it happening anytime in the near future, because current technology won’t allow it. Even if it were possible, it doesn’t seem like a great idea, because the glass is pretty much fully exposed. Not exactly good if you drop it. Cases would be another issue.
Either way, the design looks okay as far as a concept. It’s a bit awkward to look at, but we may be able to get used to it. It’s also worth remembering that doing this would make pretty much the entire front of the iPhone touch-sensitive. That’s not always good. If you’re holding the handset in your hand like you normally would, your fingers or thumb could inadvertently move things around.
