Effectively Using In-Memory Tables

Just wondering if there is anyone out there that has had any luck in effectively implementing In Memory Tables into their production systems? I have thought about making use of them as a replacement for some of the temporary/work tables we use but I am aware of the significant limitations they have in SQL 2014.

Is there a Use-Case for them yet - or should I wait it out until 2016?
