Sorry about my little rant there. On topic, the OnePlus One is definitely the sort of phone I look forward to getting in the future. I would have gotten it earlier if I had an invite before obtaining my Moto G. I could try to get an invite now and use my Moto G as backup, but the release of the LG G3 and news of the Nexus 6 has got me waiting. Also, maybe in a few years phone manufacturers will follow suit with OnePlus One's price/performance characteristics. It might not be good for me to get a OnePlus One later if that happens.
In terms of features, phones like the Moto G, Moto E, and various Nokia phones really cater to those on a budget. The OnePlus One on the other hand, scales perfectly to the asking price in the same way the Moto G has done. The OnePlus one competes with the $600 phone but can cater to those who usually get mid-tier phones. Depending on the user, I think the OnePlus One can help minimize the need for other electronics. Sure, you spend $300, but you're getting a great screen for enhanced content consumption, a good built-in camera, and amazing specs to run just about anything loaded onto the phone. Usually when I go out, I bring my Nexus 7 for better content consumption, a point-and-shoot camera to take better than average photos, and my $100 smartphone. I feel like if I just get the OnePlus One, I can eliminate the need to have all three devices with me. My camera, tablet, and phone already costs over $300 together anyway.
