It's really useful to build APIs that power mobile apps. At i.TV, we created an API with node.js to power our iPhone App that helps people know what's on TV. We use it because it scales really well and it's fun to program in JavaScript :)

LinkedIn chose Node.js to power their mobile app for similar reasons: http://venturebeat.com/2011/08/16/linkedin-node/

Node.js is stupendous with its single-thread-for-all-connection approach where each packet received is notified as event which is then handle by callback. Basically with node.js, you achieve a high level of concurrency without much multi-threading blues.
