The present day headsets are still bulky, but am sure they will become lighter and even more better.
The interface will also improve. In oculus we can already use fingers to navigate and interface with the OS. This will only improve.
I bought an Oculus Rift CV1 and it was an insulting experience. Huge amounts of enforced updates, internet connection abuse, and general Facebook shenanigans. Fool me once... I will buy one when it's an open platform or standalone peripheral. Not before.
As for open standalone platform, Lynx will soon become available. https://www.kickstarter.com/projects/stanlarroque/lynx/
Would you also pay double that amount? That's how much it costs where I live and probably in many other places too. And you can say what you want, even $300 is not an amount I want to risk going down the drain because Facebook had yet another wave of "oops you're banned now too bad" events.
I will not even touch anything Facebook for free nowadays, to be honest. It's only a matter of time until great alternatives exist.
