At this point it's not that these things aren't advances on the Raspberry Pi, it's that the barrier to entry is so low that they're coming out several times a month and there's no reason for the community to center on any one particular platform, no 'killer app' that works not just twice as well as the competition, but 20x as well. To convince the Raspberry Pi community to switch en masse, that is what we're looking for: outliers on the price/performance chart. That's hard to do at $100, from a brand nobody has heard of before, with no guarantee of substantive investment in the future of the product.
