I've actually been using Ember for quite a while now and it's formed the basis of one of our products.

Once you get over the massive learning curve with Ember and keep within the 'emberisms' (i.e. the way Ember does stuff), it's an incredibly powerful framework. In terms of hiring people to code in Ember, it's much easier to onboard people once you have a few developers that really know ember through and through. The biggest problem i've found is that for a long time the API's changed around a bit (they are fixed now) and that meant that sometimes if you're on StackOverflow, the fix may not work anymore.

Having used Backbone, Angular and Ember; I would describe Backbone as the past, Angular as the present and Ember as the future.

Ember's got some pretty big people using it, Zendesk's new agent interface is built in it, Discourse, Square and (indirectly) Apple (iCloud uses Sproutcore which is where Ember originated from).
