This is a fascinating hypothesis but I predict a big caveat: Much of Apple's quality derives from standardization. Everyone with an iPhone 4 has the same iPhone 4. You can design a case, a bicycle mount, a Twitter client or a learn-to-juggle app for the iPhone 4 and know that everyone will have the same experience.
Consider the world of free software, for example, where we have DIY manufacturing. Everyone can write their own Drupal, Wordpress, or Rails. But the market is not moving toward such bespoke products. Quite the opposite: customers want something that is based on customizations -- as minor as possible -- of a standard product.
Part of the problem, actually, is that you underestimate the effort of design. When you can turn a blueprint into hardware overnight, you'll still have to sweat over every line of that blueprint, and document it, and support it.
A standard design can be done by one person and printed by millions. That's the theory anyway.
Perhaps a more realistic scenario is that cheap manufacturing tech reduces the barrier to entry enough that small startups can mass produce affordable gadgets, without contracting everything out.
