People are going to reply to you and say "what made the iPod different from the Nomad"... inarguably the iPod was hugely successful where the Nomad wasn't.
I don't think it's a great comparison. The MP3 players in the pre-iPod era were all made by tiny players no-one had heard of. The Oculus in particular has absolutely massive backing and still hasn't amounted to a lot.
I suspect the differentiator will be software, not hardware. In particular the willingness of third parties to create software. Apple has a good record there at least.
