So here's a different perspective..
Computers went from needing multiple floors, to being in your home, then your pocket, then your hand.. ultimately it'll end up in our brains, but it must make this stop on our faces first.. this is the next phase in how we interface with computers.. it's a new space with a lot of players.. still a bit chaotic, and we'll still trying to figure out the best path forward.. still held back by technology(battery life, better and more power efficient CPU's, better connectivity etc).. it's a first glance into the future of computing.. it's going to be clunky, it's goin to have pitfalls.. but those will be tuned out as it matures.. the thing for apple here is that it creates/fosters an ecosystem where developers are incentivized to create software and experiences for this new space because no matter how much more advanced/cheaper/better the tech gets, it fails without software.. you're seeing companies who've had beef with Apple over thier AppStore % practices play hardball by not creating household apps for the platform.. YouTube, Netflix etc..
This isn't the mass market device.. that device will probably be in the price range of the MacBook Air.. it's basically a dev kit for developers that Apple are allowing its customers to also purchase.. it's just one big beta with a very high entrance fee if you have the $$ and don't want to wait a few years.
