It's got a couple of things going for it in that it's a full node, it's got a 50gh/s chip on it, and it's all integrated through some API's and runs at 5V @3A. You get very small amounts of satoshi every few minutes if you mine with it (it looked like ~200 per minute) and when you run through the setup, you get 20,000 satoshi as an "award". From a developers standpoint, it reminds me of one of those development reference boards as a test kit. Whether it's worth the $400 or not I think is more of a question of what does it do for you as an individual that you don't want to spend the time to hack together a similar solution. You've asked a great question because if you buy this as a miner, it's not worth it as an investment. However, if you buy it with the intent of using it to do some development projects, I think it's a good starter kit and closer in value.
Someone already loaded openbazaar on it: https://twitter.com/openbazaar/status/666648895922020353

I'm developing a game and plan to use any BTC it generates as rewards for the game (albeit micro faucet-like BTC, but still something). Plan to set it up later tonight using the guide on their site. Would be interested to see/hear what others are planning to do with it.
